Marcus Damon [BT12-092] [Across Time]

[Start of Your Main Phase] If you have a Digimon with [Agumon] or [Greymon] in its name in play, by paying 1 memory, for the turn, this Tamer is also treated as a 3000 DP Digimon that can't digivolve. [Your Turn] When this Tamer becomes suspended, 1 of your Digimon may digivolve into a yellow card with (Greymon] in its name in your hand without paying the cost.
