Arcane Keysmith Card Review
Looks like a powerful card on the first glance, but let’s analyze it a bit further. It’s a bit like playing Arcanologist + the Secret you drew right away. But even better, because it costs 1 less mana.
The chances to discover a specific Secret don’t look amazing – it’s only about 37.5% after Ice Block and Potion of Polymorph leave Standard (assuming no new Mage Secret – if something new gets printed the chance goes down by a few percent). On the other hand, you don’t have to put Secrets into your deck and you can still play them, which means that you can play it in a minion-based deck. Generally, Mage Secrets are pretty good. They aren’t all super powerful, but the chances are that you will see at least a single good option depending on the deck you’re running it in.
The problem is that Mage Secrets were rarely played by themselves, without other synergies. Tempo Secret Mage was a thing thanks to the cards like Medivh's Valet or Kabal Crystal Runner. Most of the Secret synergies are rotating out. Ice Block is probably the only one that was good enough to put into your deck (slower build) even if you had no synergy whatsoever, and it’s rotating out.
There’s also a fact that a 2/2 body on Turn 4 is very lackluster. If you don’t get a powerful Secret, or your opponent plays around the one you get well, you can actually lose the tempo. Not to mention that one of the advantages of putting Secrets into your deck with Arcanologist was that you cycled through your deck faster + could put only one or two specific Secrets into you deck and always get one of them.
So, as you can see, the card has its obvious upsides and downsides. I don’t think it’s as powerful as some people are saying, especially since Ice Block is rotating out, but it’s good. It should fit well into a minion-based Mage build, maybe even Big Spell Mage, since the deck doesn’t have lots of good options in the 1-4 mana slots. Or Spiteful Summoner Mage if that will be a thing, since you could technically run Secrets without flooding your deck with low cost spells.
Card rating: 7/10
