Ehther, Heavenly Monarch

When Ether enters, you may search your library for
a Monarch instant or sorcery card and put it into
the graveyard. If you do, search your library for a Monarch creature and put it onto the battlefield tapped. Return it to your hand during
the next end step.

Exile a Monarch instant or sorcery card from your graveyard: You may cast Monarch spells as though they had flash until end of turn.
