Princess Ren, Dreamborn

Dreamborn (This spell costs {1} less to cast for each
tapped creature you control.)
{u/r},{t}:Until end of turn all spells you cast have Dreamborn. If you cast a spell this turn, exile it
and put a time counter on it. If it doesn't have suspend, it gains suspend. (At the beginning of your upkeep, remove a time counter from that card. When
the last is removed, cast it without paying its mana
cost. If it's a creature, it has haste.)
