Ok, you have a lot of Rank 3 XYZ Monsters, but only 2 Level 3 Monsters. That means you can't bring out Terrorbyte. If you use the XYZ Monster 'Bahamut Shark' (Rank 4) you can summun a Rank 3 XYZ Monster, chain Number Overlay Boost to give the Number Monster (Like Terrorbyte) Material. Another Suggestion: Number 30: acid Golem. Summon him with the Effect of Bahamut Shark and chain Creature Swap. With no XYZ-Material, Number 30 deals 2000 damage every standbye phase, the owner of this card can't special summon and can't attack with the monster.
Another good Rank 3 XYZ to block Monster Effects is Black Ray Lancer, for Blocking the Graveyard take Abbysdveller (Rank 4).
Excange Black Luster Soldier with BLS- Envony of thw beginning! (Better effeckt!) And two Marauding Captains.
For Utopia: Use ZW Cards like Asura Strike!
