[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.)
