1 Apprentice with 1 Hand...? That's kinda risky, Ha. Or Bob. Or Whatever Else Comes To Mind . You might want to remove the Momongas for 1 of each (MoF too)...unless you're going for a normal summoning thing with them...but that's kind of pointless when you can bring Phoenix out from your deck anyway.

And 1 Decree with 6 traps...well, you're going to need SOMETHING to bring it back when it gets killed by SPoN. Or just max out on it.

2 Apprentice I can agree with. Not sure on 2 MoF's though.

It has worked before. Decree kills Phoenix?

[Ichaste Pekoni]

No, Phoenix kills Decree obviously. You might also want to try Dust Tornadoes...hey, do you have a side deck?

[Bleach and Sunshine]

Decree is for Return and Bottomless. So ia can see it work in there.
