I was thinking PoA myself. But future fusion is a nono right now, my mill power is prefect enough, future fusion would have no targets left by time I drew it. Trust me, play the deck, you'll see the draw and mill power is immense enough without it.
About royal decree, I don't want the deck to be slowed down with traps, I have enough trap and spell removal with lyla and ryko, msts in side. The thing I love about this deck, it's PURE SPEED, like seriously, sonic on crack is slower than this deck ._., the bad thing is, it's not as consistent as I want it to be, i need to give it that little extra push to be able to do this each duel, i just don't know what to do...
