[When Digivolving] You may reveal the top 3 cards of your deck. For each of your opponent's Digimon, you may play 1 Digimon card with [Mamemon] in its name and a memory cost of 10 or less among the revealed cards without paying its memory cost. Trash the remaining cards.[All Turns] While you have another Digimon with [Mamemon] in its name in play, this Digimon gains ＜Security Attack +1＞. (This Digimon checks 1 additional security card.)
