GoldNumemon

[On Play] [When Digivolving] Give 1 of your opponent's Digimon ＜Security A. -2＞ (This Digimon checks 2 additional security cards.) until their turn ends. Then, if this Digimon's stack has 2 or more same-level cards, this Digimon may digivolve into [PlatinumNumemon] in the hand for a digivolution cost of 4, ignoring digivolution requirements.

[Your Turn] [Once Per Turn] When this Digimon would digivolve into a Digimon card with the [CS] trait, reduce the digivolution cost by 1.
