The plan is to run a lot of minions that draw cards and hope they can grow up to be big and strong. Recurring Wingbrewer
provides a great mana sink. Azindel can be run main deck but is expensive and isn't as fun as killing people with buffed vampire bats.
and Passage of Eons
are very useful against problematic decks like Talir mask and FJS cookbook/ statuary maiden (where Killer is weak).
