If you're doing cat tribal AND running Warehouse Tabby.... might I suggest pairing it with Hungry Lynx? Warehouse Tabby makes you a rat every time an enchantment you control goes to the graveyard. Hungry Lynx makes all your cats bigger every time a rat dies. 1G: Cats you control have protection from Rats. (They can't be blocked, targeted, or dealt damage by Rats.) At the beginning of your end step, target opponent creates a 1/1 black Rat creature with deathtouch. Whenever a Rat dies, put a +1/+1 counter on each Cat you control. 2/2 And it's right at the $2 mark.
