[I Hate Snatch Steal]

 

Up to twice per turn, while there are 4 or more xyz monsters with different names in your extra deck: you can banish 2 monsters from your hand with the same level; randomly reveal 2 xyz monsters from your extra deck and your oppponent chooses 1 of them. Special summon that monster to your field and attach those banished monsters to it as xyz material. If this face-up card on the field would be destroyed by a card effect, you can detach 1 Xyz Material from a monster you control instead. (Only this card's controller can use these effects.)

 

Inspired by sphere field of course, I think it could be fun.

IDK it seams kinda OP at twice maybe once would be better

So I personally have an issue with field spells that only apply to one player. If you made it something more along the lines of this where BOTH players are able to use the effect(s) it would solve a lot of issues:

 

"The following effects can be applied to both players: Once per turn, while there are 2 or more Xyz monsters in your Extra Deck with you can banish 2 Monsters from your hand. Then your opponent randomly selects 1 Xyz monster from your Extra Deck; Special Summon it to your side of the field. Any monsters banished by this effect that would match the requirements for Xyz Summoning the monster are attached to it as Xyz material. If this face-up card on the field would be destroyed by a card effect, you can detach one Xyz material from a monster you control."

You need to say something about selecting an XYZ monster whose rank is the same as the monsters' levels. Otherwise you can just use 2 random monsters, and select 2 super-powerful XYZ monsters, and then get one of them.

XYZ monsters come out way too fast as they are, they definitely don't need a card to make them even faster.
