Rotten Remains (Blue)

Rotten Remains triggers when it resolves on the stack and becomes an attacking card. When this triggered effect resolves, you may banish a card with 1 from each hero’s graveyard. This is an optional effect. If a card with 1 from each hero’s graveyard is banished this way, the attack will get +1, then you repeat the process.

You cannot do the optional effect if you are unable to banish a card with 1 from each hero’s graveyard.

Each time you repeat the process, you may choose not to banish any cards.

If an effect prevents the attack from gaining power (e.g. Snag, Chokeslam), you still repeat the process and may continue banishing cards.
