I've been messing around with a rush paladin deck with Cho in it.. and it's pretty funny sometimes. I just played a secret mage who ended up giving me like 8 cards.I've dicked around with Cho a lot because I get a lot of enjoyment out of janky shit. He's trash even when you build a deck around him. There is no good way to make him fun in a competitive environment.
Mukla can work sometimes, I'd go with him.
If you are mostly trying to collect them all, craft elite tauren chieftain, since he isn't obtainable in packs, while the others you may luck into and get it for free.Hmm, 1600 dust and trying to plan my next Legendary.
Hunter is indeed everywhere...I was doing control warrior as well and getting the most amusing Hate filled friend requests.Hunter all over the place on ladder. Dropped Black Knight and BGH from my Control warrior and put 2x Unstable Ghouls back in. EZ life. I also had Barron Geddon in mine, and he does work as well.
