Avian Feather

[Rainbeux]

I have been working on an archtype called "Avian Feather". It is a set of Winged-Beast monsters which relies on sealing their attack to activate their effects. However I feel uncertain and these are only two of the cards from this archtype. Please give feedback.

Effect:If this card cannot attack, this card gains this effect:Once per turn you may reveal a card in your hand. If you do, you may select one face-down card your opponent controls and look at it. The same cards cannot be revealed by this effect twice.

Effect:If this card cannot attack, this card gains this effect:Once per turn you may pay 1000 Life points. If you do, destroy this card and one other card on the field.

Change your overall card effect conditions from "If this card cannot attack, this card gains this effect:" to "...this card cannot declare an attack the turn you activate this effect." This allows their effects to activate under normal circumstances (instead of off-the-wall situations where they can't attack), in exchange for not being able to attack. It'll also fit with your theme of "sealing their attacks to activate their effects".
