Killian gives you goad as an enchantress trigger, and gives you one card on any turn a creature attacks and its enchanted by an Aura you control

Once you get it to the top level though, you get to draw a card at the start of your end step you get to draw a card if you have a creature with power four or more

Its simple, but I really like the randomness of it
