So, with this, you can spew lava just like the 'lacs? I guess this could be ok with Swans of Bryn Argoll on the offensive and want an opponent-ally in a commander game to symbiotically draw...? Is it really a problem so big that Royal Assassin or Capsize can't handle? I guess if your opponent has a Silver Knight blocking your Goblin Lackey (of course you have out the king, war chief, chieftain, or something to make this trade still work out fine, unless a combat trick gets pulled) with the rig attached and you want to just slice up your Stuffy Doll.
