Harbinger Celestia Card Review

This is a weird one, not sure what to think about it. While I applaud Team 5 for a cool design, it seems to be incredibly weak. Or rather, incredibly meta-dependent. If everyone would be playing either no-minion decks or decks with only big minions, then it would be amazing. But that won’t happen.

So, for 4 mana you get a 5/6 with Stealth. That’s massive, but don’t be too happy yet, because you most likely won’t be able to use it as a 5/6. This is like a Mirror Entity, which costs 1 mana more, you can’t cheat out with Kirin Tor Mage and is not really a Secret, because your opponent knows what it is. Basically, if your opponent has any small minion in your hand, you just spent 4 mana to get it. If your opponent drops some 1-drop, or 2-drop, then you get a copy of it and that’s it.

The thing is, even most of the slow decks actually run small minions. Control Priest would be able to counter it with let’s say Wild Pyromancer, Big Spell Mage with Raven Familiar, Even Warlock with… a bunch of stuff, including Doomsayer if you have anything else on the board.

It only punishes your opponent if a) they don’t have any minions at all (rarely happens) and b) they have only big minions and can’t deal with your copy immediately. But those two scenarios don’t come up that often. In most of the matchups, and throughout most of the matches this card will be weak. Completely dead against most of the Aggro decks, unless you enjoy playing 4 mana 1/2’s.

A very specific tech card, might see play in some weird meta a while for now, but I don’t see it being usable in Boomsday. At all. Still, I give Team 5 A for the design, I wouldn’t come up with that one.

Card rating: 2/10, but it technically MIGHT be strong in certain specific matchups, so if they dominate the meta… yeah.

    Trash minion! Against Spell Hunter beneficial – otherwise not. Opponent plays a 1/1 minion and that’s it.

    * 1. Give it 3/3 + stealth + mechanic: When your opponent plays a minion add its attack and armor.

    * 2. Or give it 1/1 or 2/2 + stealth + mechanic: When your opponent plays a minion summon a copy of it.

    * 3. Or as a bait minion … give it 3/4 – no stealth + mechanic: When your opponent plays a minion summon a copy of it.

    This will at least force the enemy to deal with it wasting mana before dumping a minion on the board. Thus slowing tempo.


    Until we get another expansion I can’t dust it – I won’t risk getting it again. I guess this says it all. Just as useless as when they nerfed Patches the pirate.

    In hsreplays.net is not shown on any deck on anyone in the world.

    I think it should be ‘after your opponent plays a legendary minion, become a copy of it’.
    That way, it can retain some benefit.

    Legendary that Weaker than common card. Even normal mage trap card (mirror entity) is much better.
    Only 3 mana & didnt let your opponent know what trap u play.

    This is a tech card agains’t spell decks that could dominate the meta. In a future it can became good, just not now.

    Would be good if it was like shifter zerus or chameleos, but from the wording it just seems to be a bad mirror entity

    I don’t think this will see any play at all… but I am obsessed with the artwork. I hope I get it golden if just for that.

    She still can play in Druid with Oaken, 4 mana for 5/6 and 6 armor not bat actually.

    does no one realise the fact it might be a malygos druid tech in the mirror?
    ur opponent wont be able to drop maly on turn 9 now becuase it will kill him next turn.
    although its mostly a bad cards this is maybe the only meta for this to work(because obiously there will be maly druid).

    Wow, what an incredible card, if you play aggro and tempo it forces your opponent to make a bad play, i think this is better then mirror entity. No idea why is it so downrated, i gave it 5 to up its record back to where it should be, i would probably play it in an aggro or tempo deck if i am not playing odd.

      People just can’t think out of the box.
      If you have a table full of low health minions and it will be opponent turn 5, you play this. If he plays a weak minion you save your table, if he plays volcano you leave with 1 or 2 minions.

    mandatory trash legendary

    I might not be able to see it’s full potential, but to me right now, this seems like the worst legendary ever printed. It’s basically a 4 mana Mirror Entity. The difference is that it can’t be cheated out with spell discounts like Mirror Entity and your opponent knows what “secret” you just played. Even if your opponent can’t play a minion or only got big minions to play, a 4 mana 5/6 isn’t something that alone wins you the game, it’s well stated disregarding the effect yes, but not game defining. Additionally it got no synergies that allows it to be a fun asset in gimmick decks. This seems like a thrash epic more than a legendary to me.
    1/5 just because I can’t go lower than that.

      Youre wrong,we cannot play a lot of mirror entity everygame like we can do with a minion,and nobody have 3 or more cheap minions after late game,yeah,late game,thats the moment we will use Celestia
      Theres a lot of cards that copies a minion,in this case Celestia,and we can use this strategy to counter enemy board with one or two Celestias per turn
      Lab recruiter is one example,its a card that can be used in a lot of decks,so we doesnt spend 3,4 or 5 slots to done the combo,we just use a single slot to put Celestia on,and you can get a lot of value in late game

        I did write in the beginning that I might not be able to see it’s full potential. From what you wrote, I might admit that I still struggle to see what you find fascinating about it. Time will tell though if this card will be any good at all, and I hope that I’m wrong, because I love a good surprise.

          When i look some legendary cards i get decepcioned too,but them i think about Its potential
          In this case,i mean Celestia can take a single slot in a deck that already have cards that copy minions,a slot that you would spend with a “deck filler” card,or a weaker card that doesnt does great things
          Copy her is the only situation i can think it get potential,but it can be very strong
          In some games,it can just force your opponent to summon the “wrong minions”,it can broken some combos and remove cards that would make a big value

            Decks that play big minions most commonly got synergies to actually harvest their true potential. Big Priest got spells to summon their minions, you won’t get any value from otk decks as they play their big minions on the turn you die, cube lock got ways to recruit or even summon their big minions from hand, and Togwaggle druid steals everything you copy to your deck gaining you a 5/5 minion that isn’t even posing a thread. Not to say Hearthstone is mostly dominated by aggro players, and with these small mechs printed I’m assuming the aggro players will be plentiful. This card is terrible in a match up against aggro. This is all speculations and I hope that it will find its place, but I’m not getting my hopes up for this one.

            I like your optimism by the way and I hope you will be right! I’m just a pessimist towards this one.

      Sure you can!

      I give it a -2.86/5.

    Probably the real reason to play this card is an attempt to ”deny” your opponent next play/turn.

    Still, pretty bad card. 1/5

    Interesting card. Obviously easy to play around. Thinking about evolve shaman, it seems this effect will still activate regardless of how this lands on the board. Could be good to delay combos probably not break them though.

    Who knows? Maybe this card can be really bad or maybe it can be really good. Looks really bad right now but if it keeps it’s stats it’s not that bad of a tempo play since it’s 4 Mana 5/6

    Harbinger Celestia has some applications, but those applications would only come about if either you’re playing against an idiot or you’ve timed when you’re opponent would need to play a Lich King level card perfectly.

    Either that or Spell Hunter is everywhere.

    No one has mentioned the Top Tier, Meta Breaking, OP Silence Priest?

    Does it keep the stealth between transformations? Because if it does it would at least least be an interesting card

    The neutral legendaries should be better than this.. these cards are laughably bad for legendaries.

    • DyingHawk

      I don’t think it should have to do with power level, Mecha’thun is obviously weak but super cool. This on the hand I can agree with you on, this is a card we’ve already seen before (mirror entity), but it is not secret, and costs 1 extra mana, which would be okay if mirror entity wasn’t already a card that never saw any play

      • Bazinga
        August 1, 2018 at 12:24 pm

        “which would be okay if mirror entity wasn’t already a card that never saw any play”

        You’re new to hearthstone aren’t you? Mirror entity saw a ton of play since release, in secret mage, tempo mage, aggro mage, control mage, basically every single mage deck ever created, up until the average mage card value was inflated to shit with cards like firelands portal or explo runes.

          August 1, 2018 at 12:51 pm

          I’ve been playing for 2 and half years, “ever” was an exaggeration but it certainly hasn’t been played in 2 years. And if it has been power creeped off the face of the earth my point still stands, they made a CURRENTLY unplayable card worse and made it legendary
