OCG Fix needed - Wind monsters WIP

[Kazuki Shuheiwa]

Here is the lore of two monsters I'm planning to do:

 

Gensoratengu Servant Warrior

You can Tribute this card to Special Summon 1 "Gensoratengu, Tengu King" from your hand.

 

Gensoratengu, Tengu King

If this monster has been Summoned by the effect of "Gensoratengu Servant Warrior", all WIND monsters you control increase their ATK by 300 (except this card). You may discard your hand to destroy all of your opponent's face-down monsters on his Field.

 

Any fixes needed?

The last one needs a few minor fixes.

 

If this card was Special Summoned by "Gensoratengu Servant Warrior", all WIND monsters you control (except this card) gain 300 ATK. You can discard your hand to destroy all face-down monsters your opponent controls.
