Rennala, Carian Queen

Magecraft — Whenever you cast or copy an instant or sorcery spell, draw a card, then discard
a card.
{1}{t}: Create a token that's a copy of another target nonlegendary creature you control, except it has haste. Sacrifice it at the beginning of the next
end step.

"Oh little Ranni, my dear daughter. Weave thy
night into being."
