Anoint with Affliction

Instant

Exile target creature if it has mana value 3 or less.
Corrupted — Exile that creature instead if its controller has three or more poison counters.

Many vatkeepers use necrogen etchings to judge the value of their aspirants. If the wounds rot and fester, the recipient is not worth further effort.

2023-02-04 As Anoint with Affliction resolves, if the creature's controller has three or more poison counters, the creature will be exiled no matter what its mana value is. If the controller doesn't, the creature will be exiled only if its mana value is 3 or less.
2023-02-04 You may choose to target a creature that has mana value greater than 3 even if no player has three of more poison counters.
