Creature â Human Cleric
When Extricator of Sin enters the battlefield, you may sacrifice another permanent. If you do, create a 3/2 colorless Eldrazi Horror creature token.
Delirium â€” At the beginning of your upkeep, if there are four or more card types among cards in your graveyard, transform Extricator of Sin.

While resolving Extricator of Sinâ€™s first ability, you canâ€™t sacrifice multiple permanents to get multiple Eldrazi Horror tokens.
