Pretty Liar [R]

ONSTAGE [b][b]
Reveal the top 2 cards of your deck. If they are the same rarity ([R], [SR], or [SSR]) you may put 1 card BACKSTAGE face down and the other in your hand. If they are not the same rarity or your BACKSTAGE is full, discard them.

Farfin says: It can feel pretty bad to end up discarding the card you need on an unlucky reveal but Syuko Shiomi [SR] can get the discarded cards back into your hand.
