I like the Surviva-din a lot, although I’m not sure how effective it is. Last month’s iteration got me comfortably into 10-9 ranks (which is farther than I’ve gotten otherwise).
A lot of my changes are direct responses to bad matchups I’ve been having (control priest and miracle rogue, mostly), so I’ve been trying to push it a little more aggro. The danger there being I may just be hitting my skill ceiling. I think there’s just some learning about how to play the deck better (for instance, I think I need to ignore Northshire Clerics when playing against priest in favor of moar facepunch). Divine Favor is a direct result of that, for instance. I may need to become more rigorous, because thanks to vividness bias, I think I’m trying to fix problems without really thinking about how they affect what is working.
I very rarely find myself stranded with divine favor, but I think that my deck is a little more small-cost aggro than yours, which means I’m out of cards more often. I also just personally hate having an empty hand: a) it isn’t fun to not play cards, b) I feel like it lets my opponent act with impunity because he knows I don’t have any tricks up my sleeve, c) I always seem to lose top-decking races, possibly due to lack of Legendaries. If I get 2 cards (equal to arcane intellect), I consider it acceptable, anything else is gravy.
Youthful Brewmaster is probably more fun than good. He has potential to be very very annoying. The combination of Abusive Sergeant, Argent Defender, and Brewmaster has the potential to be hilarious. They’re cheap enough that you can drop the same one multiple times the same turn, or if one’s already on the board, face-punch, then pull back to your hand, then re-play for extra battlecry without losing an attack. 2 might be too many. I liked having one though, because I didn’t have enough turn 1 / 2 drops (Haunted Creeper doesn’t have enough presence on the board, and Harvest Golem, at 3, competes with the Crusaders, who I like more). He’s basically a bloodfen raptor turn 2, and hilarious combo potential after that.
I have trouble with Frostwolf Warlord, because I hate dropping him when I think mayyyybe I’ll get one more +1 out of him next turn, and then I lose my chance, but that’s just a mental block. FW is never bigger than sea giant, but sea giant is occasionally cheaper than FW. I never get much out of either, to be honest. At the end of the day, they’re both basically just hard-removal bait.
I’ll probably keep tweaking it for a while. (I keep meaning to swap Jungle Panther for Shade of Naxxramas. Seems like only upside to me.)
Unrelatedly, I made a Warlock Zoo deck without looking it up online, based purely on looking at the decks I played against, and it seems pretty serviceable. It’s funny how consistent that deck is.
