Bet you forgot Call to Arms existed.

Well, forget no more because this bad boy is now the centerpiece of an OTK package that requires only two drawn cards.  Here, Call to Arms here can only summon Garrison Commander and Sing-Along Buddy, and will always give you one of each.  So your main goal is to pop Uther of the Ebon Blade on turn nine, then empty your board, play Call to Arms (or GC + SAB if you have both in hand), and hero power twice to summon all four horsemen in one turn with no setup apart from playing Uther.  Disgusting!  How can we make it worse?

Well, that’s what the Silver Hand is for.  These guys are just the distraction, so you can go crazy with recruits to keep the opponent from building up their own board - so crazy that you might even win before your inevitable turn 9 Uther.

You have favorable matchups against Reno decks (recruits can outpace them), and other combo decks (your combo is much faster).  Decks that run board clears and combo breakers are trouble, as are midrange decks that can reliably clear your board and still kill you on turn 8-9.

As for mulligans - I usually go for Uther and Call to Arms at all costs.  The only other card I keep is Lost in the Jungle to have a turn 1 play.
