[Main] Play 1 purple level 4 or lower Digimon card from your trash without paying its memory cost. Then, if you have a Digimon with [Myotismon] in its name in play, 1 of your Digimon gains [Blocker] until the end of your opponent's next turn. (When an opponent's Digimon attacks, you may suspend this Digimon to force the opponent to attack it instead.)
