Elianora, Light of the Dawn

First Strike, Vigilance
At the beginning of combat on your turn, if a creature you control has the same color identity
as Elianora, Light of the Dawn, you may pay {r/w}{r/w}{r/w}. If you do, Elianora gains that creature's
abilities until end of turn. You cannot
choose more than one target, and cannot choose
the same target until after your next turn.
When a creature you control attacks, you may
draw a card. If you do, discard a card.
