Dragons are pretty good currently, but I expect them to get hit in the September ban list.
Anyway, here is a new one.
Mermail - Gaioabyss
2 Level 7 WATER monsters
While this card is face-up on the field with Xyz Material, Level 5 or higher monsters cannot attack. Once per turn, during either player's turn: You can detach 1 Xyz Material from this card; negate the effects of all monsters your opponent controls whose ATK are lower than this card's ATK, until the End Phase.
... interesting. Waters really getting a push in the next few sets, not as much as warriors though.
