Tamer

[Start of Your Main Phase] If you have a Digimon with the [Free] trait or a Tamer with [Ken Ichijoji] in its name in play, gain 1 memory.
[Your Turn] When one of your 2-color blue and green Digimon attacks, by suspending this Tamer, digivolve that Digimon into a Digimon card with [Imperialdramon] in its name in your hand for its digivolution cost.

[Security] Play this card without paying its memory cost.
