Kemi’s “Special” Pouch

Whenever a nonland card you own is put in exile, put a containment counter on it.
{r}{u}{t}: Draw a card, then exile a card from your hand.
{u/r}{u/r}{t}, Remove a Containment counter
from a card you own: Copy that card. You
may cast that copy. (A copy of a permanent spell becomes a token.)
