Saintly Sepulcher

Whenever creatures you control are sent to a graveyard, you may instead place them under
Saintly Sepulcher and place a 1/1 Spirit token
with Flying onto the battlefield.
Each creature under it reduces the activated
ability of Saintly Sepulcher by {1}.
{10}, Sacrifice Saintly Sepulcher: Return all
creatures under Saintly Sepulcher to
your Library and shuffle it.
