Blizzard makes some pretty good games. Hearthstone's fun, heard some good things about Overwatch. I think they did mess up with Heroes of the Storm, though.
Since zoolock has been my favorite deck for quite a while, I made a variation of it. Turns out it's extremely strong against all the new late-game decks, with minions that stick around even after board clear. I've gotten several quick victories with it. Everyone's conceding so fast right now.
I believe that Blade of C'thun is a bit ridiculous... It's a 4 mana 4/4 that buffs C'thun for a chosen amount, and Assassinate rolled into its battlecry.
Also, my favorite card is MARVEL AT HIS MIGHT!
No, it's actually Ragnaros. The Firelord.
