Sin, Unending Cataclysm

Legendary Creature — Leviathan Avatar

Sin wants a deck that sacrifices its own creatures to drain opponents' life. It also works in a deck built around Avatars or Sea Monsters.

As Sin enters, remove all counters from any number of artifacts, creatures, and enchantments. Sin enters with X +1/+1 counters on it, where X is twice the number of counters removed this way.

When Sin dies, put its counters on target creature you control, then shuffle this card into its owner's library.

Wizards of the Coast 6 Jun 2025

If the target creature is an illegal target as Sin's last ability tries to resolve, it won't resolve and none of its effects will happen. Sin will remain in the zone it went to when it died (which is usually the graveyard).

Wizards of the Coast 6 Jun 2025

In some unusual cases, you may end up putting the appropriate counters on more than one permanent. For example, if you control The Ozolith ("Whenever a creature you control leaves the battlefield, if it had counters on it, put those counters on The Ozolith.") when Sin's last ability resolves, you'll put the appropriate number of each kind of counter onto both The Ozolith and the target creature.

Wizards of the Coast 6 Jun 2025

Sin's last ability doesn't cause you to move counters from Sin onto the target creature. Rather, you put the same number of each kind of counter Sin had when it died onto the target creature.

Wizards of the Coast 6 Jun 2025

Sin's last ability puts all counters that were on Sin onto the target creature, not just its +1/+1 counters.

Color identityEvery color of mana symbol on a card, in its cost and in its rules text. Your commander's color identity sets the limit for your whole deck: every other card has to fit inside it. A deck led by a green and white commander cannot play a card with any blue in its color identity.Open the full glossaryUGPlayers write colors as letters: U for blue, G for green. Blue is U because B was already taken by black.AristocratsAristocrats decks sacrifice their own creatures on purpose and profit every time one dies, often by draining life from each opponent.
