3 Level 9 monsters
Cannot be destroyed by battle except with "Number" monsters. You can Tribute 2 other monsters that have not attacked this turn; this card can attack 3 times during each Battle Phase this turn. If this card is Xyz Summoned by Ranking Up "Number 107: Galaxy-Eyes Tachyon Dragon", it gains this effect.
● You can detach 1 Xyz Material from this card; negate the effects of all other cards currently on the field, until the End Phase, also return all other cards that were used during this turn to the same location (hand, field, Graveyard, Deck) and position they were in at the start of this turn (cards that were already banished at the start of the turn are now banished). You choose which of the cards affected by this effect can be used during this turn.

Straight from the Yugioh Wiki. I feel bad knowing that I'm going to try and script that..

Don't feel bad Jack. If you can't do it, nobody can.

Oh don't worry, I'm almost done with it actually.

If it makes you feel better, when the real card is released, I'm sure the effect will be simpler.

But I know you're doing this in preparation, thank you and keep up the good work.
