Flying You may have this creature enter as a copy of any creature on the battlefield with mana value less than or equal to the amount of mana spent to cast this creature, except it's a Bird in addition to its other types and it has flying.

Whenever one or more other creatures you control leave the battlefield without dying, draw a card. {1}{U}, {T}: Return another target creature you control to its owner's hand.

Flying When Wingbright Thief enters, target opponent reveals each nonland card in their hand. You choose one of them. That card perpetually gains "When you cast this spell, each opponent draws a card and gains 3 life."

(As this Saga enters and after your draw step, add a lore counter. Sacrifice after III.) I — Crescent Fang — Search your library for a basic land card, put it onto the battlefield tapped, then shuffle. II — Heavenward Howl — When you next cast a creature spell this turn, that creature enters with an additional +1/+1 counter on it. III — Ecliptic Growl — Draw a card if you control the creature with the greatest power or tied for the greatest power.

Flying Whenever you cast a creature spell without flying, conjure a duplicate of it into your hand. The duplicate perpetually gains flying. This ability triggers only once each turn.

When this creature enters, exile up to one target non-Assassin creature until this creature leaves the battlefield. Warp {1}{W} (You may cast this card from your hand for its warp cost. Exile this creature at the beginning of the next end step, then you may cast it from exile on a later turn.)

Counter target noncreature spell. Its controller creates two Treasure tokens. (They're artifacts with "{T}, Sacrifice this token: Add one mana of any color.")

Destroy target artifact, enchantment, or creature with power 4 or greater.

Destroy all creatures. You gain 1 life for each creature destroyed this way.

({T}: Add {W}.)

({T}: Add {U}.)

({T}: Add {G}.)

{T}, Sacrifice this land: Search your library for a basic land card, put it onto the battlefield tapped, then shuffle. Then if you control four or more lands, untap that land.

This land enters tapped unless you control a Plains or an Island. {T}: Add {W} or {U}.
