anyway it should be impossible to draw a rare after a quick (unless the Aria bonus is triggered)
You did pretty well using only ninja, I probably would focus the deck entirly on it:
second chance, auxilia, wish, dark flame and pegasus to draw it as quickly as possible, halfling rouge to duplicate it and some uncommon and rare durable to protect it from banish. also mediator and black market could be useful. with so many zero cost you may want to add also moon shrine.
with a wise choice of your rares also confusion could fit well (wouldn't it be lovely if he use whallala?)
oh well. I'm gonna make this deck.
