If I don't have a level 4 or lower purple or yellow Digimon card in my trash, do both players still trash the top card of their security stack from this card's [When Digivolving] effect?
If either or both players have empty security stacks, can I use this card's [When Digivolving] effect to play a level 4 or lower purple or yellow Digimon card from my trash?
