There is something truly special in Saviors of Uldum. A card Peter “LegendaryFerret” Whalen has called his favorite Hearthstone card, surpassing Whizbang the Wonderful. A card Chadd “Celestalon” Nervig tweeted is his “favorite card that we’ve ever made.”
The card, the mystery, the legend. Zephrys the Great.
In this article, we’ll explain in detail everything you need to know about Zephrys. Let’s go!
Zephrys is not very self-explanatory. “If your deck has no duplicates, wish for the perfect card.” What is that even supposed to mean?
Zephrys’ Battlecry is actually a Discover effect. It offers you three cards to choose from, and these cards can be any cards from Basic and Classic sets – and from any class, unlike regular Discover. There is, however, one limitation: Zephrys does not offer cards that allow you to replay it, such as Shadowstep and Youthful Brewmaster. If it offered Shadowstep, there would be a rather hilarious OTK with Knife Juggler on turn 4. Yeah, it’s probably for the best that it does not exist.
There is a complicated algorithm behind Zephrys that attempts to determine the best possible cards for your current situation. It looks at several variables, such as your mana, the board state, classes, and how many cards each player has in their hand. However, it does not look at what cards you have in your hand, so if there is a combo you could pull off with cards in your hand, Zephrys does not know about that. The first rule of playing with Zephrys is to work together with it: make plays from your hand first if you want to help Zephrys find a specific card for you.
Zephrys likes to win games, so it will always look for lethal. However, Zephrys is extremely risk-averse. If there is any way to have 100% lethal (remember, it does not check your hand!), Zephrys will give it to you. If there is the smallest chance to fail, it might not. For example:
- If your opponent is at 12 health, you are at 10 mana, and you have a Fireball in hand, play the Fireball first to set the opponent to 6 health and then play Zephrys the Great, and it will always offer you another Fireball. If you play Zephrys the Great first, it might not offer you the Fireball, because it does not know your hand.
- If your opponent is Lord Jaraxxus, Zephrys will always offer you a Sacrificial Pact.
- If you have a frozen minion that could hit for lethal, Zephrys will offer you a Silence.
- In one of the pre-release streams, there was a situation where the opponent was at 7 health and had a 1/1 minion and a 3/2 Zilliax on the board for a total of 10 health. The player had two attack on the board. Zephrys did not offer Avenging Wrath, because if it does not kill the Zilliax, it would not be lethal. Instead, Zephrys offered Pyroblast for potential lethal next turn.
Zephrys emphasizes cards that you can play immediately. You can affect the cards you are offered by spending or not spending your mana. If you play Zephrys on curve on turn two, it will offer you some good three-drops to play next turn. However, it likes to offer you cards you can play on the current turn whenever possible, and while it often offers at least one card for next turn, cards to play next turn are a lower priority for it. If you are at low health and want to become Lord Jaraxxus, spend some mana first to incentivize Zephrys to look for more cards for next turn.
Under the hood, Zephrys runs simulations, but it is not a machine learning algorithm. As you learn what Zephrys likes to offer you, you can be confident that this knowledge will remain useful, its preferences will not change.
Overall, Zephrys is a major game changer for Highlander decks. It means that every Highlander deck has potential access to a number of powerful plays on any turn:
- Bloodlust and Savage Roar are available if the deck ever has a wide board.
- Mass Dispel is always a threat and can push through multiple Taunt minions.
- Sinister Strike, Fireball, Avenging Wrath, Pyroblast, and other cards provide direct damage.
- Hex and Polymorph can deal with Deathrattle minions.
- Hellfire, Blizzard, Flamestrike, Twisting Nether, and other cards can wipe entire boards.
- Arcane Intellect, Sprint, and Lay on Hands can draw cards.
- Lay on Hands, Healing Touch, and Holy Light can provide emergency healing.
The original Reno Jackson only healed you to full health. Zephrys the Great goes far beyond that, the examples above are a mere fraction of its capabilities. The real question is whether Zephrys alone is worth building Highlander decks even for classes with no other synergy cards. In some cases, it just might be.
