I went through a phase where all my decks were about using the opponent's resources against them
It's up to you to decide whether you want a cheaper commander that draws cards and makes beefy tokens, or a commander that triggers lifegain payoffs, recurs, and voltron kills
It also does 20 DMG to itself but you have Potions for that
I wouldnt get excited by a 4-mana draw-three normally, but you dont need to worry about casting the cards until next turn, and getting a burst of free cards gives you enough of an advantage to push a close game in your favor
