Bet you've never seen a deck like this before...

- 2 Solemn Judgement
+ 1 Ultimate Offering
+ 1 Giant Trunade

- Cyber Pheonix
+ Sangan (Basically a staple with as many searchable cards as you do)

You can't pass up the opportunity to have an Ultimate Offering in this deck. Ultimate Offering + Limiter Removal + Gadgets = Game (But make sure you can't get pwnd by their traps).

Hope that helped.

Can you use UO as many times as you can pay per turn?

Yes, but it has to be during your main phase 1.

Correction, Either of your main phase's OR your opponents battle phase.

Oh, all this time I was under the impression that it was ONCE a turn.

I don't like Ultimate Offering, it's a useless dead draw late game. It seems like a good risky OTK, but I prefer to stick to the theme. I used to run Sangan, but besides Gadgets, which I run 9 of, there isn't much. That and I waste a summon, which makes it very slow, when I could be summoning out Snipe, whose effect I get immediately.

Don't dismiss Ultimate Offering until you've tested it out, but if you still don't like it, then don't use it.
