7-1 so far with my first tgt draft (started the moment tgt came out, still working on it).
Priest deck btw.
Special mentions... (from tgt only)
Kodorider, generally two 3/6 for 8 mana and almost always getting value off the heal as well. I've had this snowball or at least keep me in the game even though my deck doesn't have card draw.
North Sea Kraken, this guy is a beast (no not technically a beast) since that 4 damage will often remove a minion (my opponent has often plenty since I only have 1 holy nova) and then he helps close out a match, smacking for 9 damage. Amazing top deck.
Pit Fighter, yeti smasher, senjin killer, kills many 4 drops for free, has a ton of hp to survive with afterwards, very hard to deal with efficiently.
Master Jouster, even when the joust fails, he is a pit fighter for 1 mana more. When it succeeds, that divine shield and taunt is very nice.
Silent Knight, Vellen's chosen synergy, dark cultist synergy, shattered sun cleric synergy, and just all around very solid tbh. If you think of how good minibot is in arena especially when you drop a buff on him, for 1 mana more give him stealth to enable that to happen almost always... god it is good. It even puts that 4/2 stealth beast to shame.
TGT cards are pretty good in arena it seems.
