SaviorHuckmon (BT13-016) - Versus Royal Knights

[Your Turn] When you play a Digimon with [Sistermon] in its name, this Digimon may digivolve into a Digimon card with [Jesmon] in its name in the hand for the digivolution cost. When this Digimon would digivolve by this effect, reduce the digivolution cost by 2.

[When Attacking] [Once Per Turn] If this Digimon has the [Royal Knight] trait, you may play 1 Digimon card with [Sistermon] in its name from your hand or trash without paying the cost.
