I haven't seen a deck use Transtarn or Trick Archfiend before. Nice I guess. The Extra look good, but shouldn't you run 3 Instant Fusion? And is the Archfiend Palace really necessary?
take out The infernity support cards since you only have 6 Infernitys in your deck
+2-3 Compusory Evac
+2 Divine Wrath
Other than that the main problem is that you have 13 monsters.......in an xyz deck......
You do know that this is a new version of the Infernity deck right? Its pretty popular right now. His monster line up is just fine and the support cards are necessary
