I think you need to change vamp dagger with pulvy/eternity and add in a miracle.
I have tried both, but the pulvy isnt really needed, since you have a chimera and there arent really any other permanents to worry about. The only one I can think of is the catapults from Osiris, but you would need your pulvy early then, which isnt likely with one.
Also the eternity isnt very useful, since cells are generated at the end of the opponents turn, giving him the chance to play another creature, which every FG does, because they always have the quanta for it. It could be useful vs golems, firemaster and such, ill give you that, but it also uses a lot of time quanta, which is needed for your hourglasses.
Ive never needed a miracle, except in early game, but you wouldnt have the quanta for it anyway.
Come to think of it, I will do a bit of testing with an EE instead of a dagger. *Tested and doesnt work, dagger is the way to go*
