Q1: When a Digimon with this card in its digivolution cards performs a security check, if the checked card is a Digimon card or a Tamer card, does that card's Security effect activate?
Yes. All Security effects on non-Option cards activate normally.
Q2: When I use this card's Main effect to digivolve Takuya Kanbara as a level 4 red Digimon, can I digivolve by paying a cost of 4 using the standard digivolution requirements?
No, you can't. If digivolution is performed using the Main effect, you must digivolve for a digivolution cost of 3.
