Legendary Creature â Human Knight
, : Create a 2/2 white Knight creature token with vigilance.
, , Tap X untapped Knights you control: Destroy target creature with power X or less.
You can tap any untapped Knights you control, including ones you havenâ€™t controlled continuously since the beginning of your most recent turn, to pay the cost of Aryelâ€™s last ability. However, you must have controlled Aryel continuously since the beginning of your most recent turn in order to use either of its activated abilities.
Tapping Aryel to activate either of its abilities while itâ€™s attacking doesnâ€™t remove it from combat.
Once you announce that youâ€™re activating Aryelâ€™s last ability, no player may take other actions until the abilityâ€™s been paid for. Notably, players canâ€™t try to make the value of X invalid by removing or tapping your Knights.
If the target creatureâ€™s power is greater than X as Aryelâ€™s last ability tries to resolve, the ability doesnâ€™t resolve. You canâ€™t tap extra Knights once the ability has been activated.
