King Ramses, The Forsaken

When King Ramses enters, target opponent
creates The Slab, a legendary colorless
artifact token with "{4}, {t}, Pay 3 life: Target
player gains control of The Slab."

At the beginning of each opponent's upkeep,
if that player controls a permanent named
The Slab, search your library for a Curse card
and attach it to that player, then shuffle.

"Return the Slaabbb."
