Special Summon 1 "U.A." monster from your Deck, but its effects are negated, also it cannot be used as Synchro or Xyz Material for a Summon. Then you lose LP equal to the Level of the monster you Special Summoned by this effect x 300. You can only activate 1 "U.A. Signing Deal" per turn.

Special Summons from your Deck / Cannot be used as a Synchro Material Monster / Cannot be used as an Xyz Material
Does U.A. have any potential to be really good? Or will it just be mermails and the good decks right now (fur hire, masked hero, amazoness)? This looks really cool and I don't really like using water decks.
Well UA monsters used a lot of high lvl monster. So it must be a problem for the archetype to be good in DL format. You would have to use some special summon like vassal, or any special summon to help them in their consistency.
