[When Digivolving] You may place up to 2 [Vemmon] from your trash as this Digimon's bottom digivolution cards.
[End of Your Turn] If this Digimon has 4 or more digivolution cards, it may digivolve into a Digimon card with [Vemmon] in its text in the hand.
[[DigiXros -1] 4 [Vemmon]
When this would be played, you may place specified cards from the hand/ battle area under it. Each one reduces the play cost.]
