Arkham Shopkeep

Eminence — You have shroud. If you would lose
life, you may instead sacrifice a Gold token for
each 1 life that would be lost.
Shroud, Wither
You may tap a nonland permanent you control
to have an opponent gain control of it.
If you do, gain X life and create X Gold tokens,
where X is equal to that permanant's converted
mana cost.
