Crest Mark [Attack On Titan: Final Season]

If you do not have a character with "Mikasa" in its card name, this card cannot be played from your hand. Look at up to X cards from the top of your deck, choose up to 1 card from among them, put it into your hand, and put the rest into your waiting room. X is equal to the number of "Eldian" or "Corps" characters you have +1.
