Kellan, the Fae-Blooded // Birthright Boon

Target creature gets -X/-X until end of turn. That creature gets an additional -3/-3 until end of turn if you controlled a Faerie as you cast this spell.

Flying Other creatures you control that are enchanted by Auras you control have base power and toughness 4/4 and have flying.

Bargain (You may sacrifice an artifact, enchantment, or token as you cast this spell.) Target creature gets +2/+2 until end of turn. If this spell was bargained, that creature also gains flying and lifelink until end of turn.

Celebration — This creature gets +0/+2 as long as two or more nonland permanents entered the battlefield under your control this turn.

Destroy target enchantment. If a permanent you controlled or a token was destroyed this way, draw a card.

Flying When this creature enters, create a Royal Role token attached to another target creature you control. (If you control another Role on it, put that one into the graveyard. Enchanted creature gets +1/+1 and has ward 1.)
