[On Play] [When Digivolving] Trash the top 2 cards of your deck. Then, this Digimon gains [Raid] and [Retaliation] until your opponent's turn ends.
[When Attacking] [Once Per Turn] This Digimon may digivolve into a Digimon card with [Megidramon] or [ChaosGallantmon] in its name in the hand. For every 10 total cards in both players' trashes, reduce this effect's digivolution cost by 1.
