Heroes.DEK

Okay, what we have in this deck is:

2x Ice Edge
3x Alius
3x Ocean
Prisma
Stratos
Voltic
2x Wildheart
2x Snowman Eater

Book Of Moon
Dark Hole
2x E - Emergency Call
Future Fusion
Giant Trunade
3x Miracle Fusion
Monster Reborn
2x MST
3x POD
ROTA
3x Super Polymerization

Royal Oppression
Solemn Judgement
2x Solemn Warning
Torrential Tribute
Trap Stun

3x Absolute Zero , The Shining
2x Escuridao, Gaia, Great Tornado
Nova Master
Wild Wingman
Vision Hero Trinity

I would like to try and fit in some XYZs but I'm not sure what. I have no idea why prisma (all require Elemental Heroes and different attributes) and wild wingman (doesn't seem to be summonable) are there. What should I get rid of and what should I put in it's place. And would Oversoul and Righteous Justice come in handy? Pre-emptive thanks.

So yeah, Wingman can go, add 2-3 Absolute Zero in Extra Deck, Gaia too.

Already explained about R & O, Prisma helps set up Miracle Fusion, and you can always use it for Omni's. Deck seems ok though.
