Designed to overwhelm via number of attackers out. Combined with regen, Friar Jimmy, and Stan The Great, typically low health attackers become nearly unstoppable.
Hercules Clyde is great at neutralizing Stan of many moons which can kill everyone out on the floor.
Terrance, Nathan and Rogue Token do a great job against flying enemies and swarms.
Princess Kenny and Underpants Gnomes come in handy as low mana cards to put out in a pinch.
You can sub gnomes for Paladin Butters if you prefer, or even Catapult Timmy for even more swarm action!
