Linaya, the Astromancer

{1}, {t}: Target instant or sorcery spell's owner
may exile it with a star counter on it as it resolves
this turn.
Constellation—Whenever an enchantment enters
the battlefield under your control, each player
may choose a card they own in exile with a star
counter on it. If they do, they remove all star
counters from that card and cast a copy of it
without paying its mana cost.
