At the beginning of combat on your turn, you
may have target Elemental creature you control
get +1/+0 and gain first strike until end of turn.
Whenever a source you control deals damage to
an opponent, Elysia, the Eternal Flame deals 1
damage to each creature and each planeswalker
that player controls.
