Expansion has been out a bit, we've had some experience, although still limited of course, but I really wanted to talk about this card, and figured I would broaden the topic so this can be a place for people to talk about their favorite new cards (also because it's way more cool to exchange ideas than to not do that, especially on a forum).
Absolute favorite for me so far: Mindlathe.
This card is amazing!
It can turn the tables so fast so hard! Sure, you'll take damage, but it's very very often worth it because quite often you can make sure the minion kills itself against the enemy general.
It must be incredibly amazing against Celerity minions, haven't had that happen yet, but I am looking forward to it!
Even as defense it's great, if the enemy does decide to hit your general with it equipped you get the minion as yours until the end of your turn, so you can use those minions anyhow.
I think I will always just put 2 in my Abyssian decks, I really think this will be staple, at least for me.
Sure, sometimes you'll have to cycle it since it's not good in that particular circumstance, but I think those situations are quite rare.
So, what about you? What is your favorite card so far?
