Leopardmon

[When Digivolving] [Main] [Once Per Turn] You may play 1 Digimon card with the [Royal Knight] trait or 1 green Digimon card from your hand for its play cost. When played by this effect, reduce the play cost by 4. [All Turns] When you play another Digimon, all of your Digimon with the [Royal Knight] trait and all your green Digimon gain ＜Blocker＞ (At blocker timing, by suspending this Digimon, it becomes the attack target) until the end of your opponent's turn.
