Tomb of the First Trickster

Tomb of the First Trickster enters the battlefield
with ten Rite counters on it.
Put a card in exile with a dream counter on it
into its owner's graveyard: Remove a Rite counter
from Tomb of the First Trickster.
When Tomb of the First Trickster has no Rite
counters on it, sacrifice it. When you do, search
your library and/or cards you own outside the
game for a card and dream it.
