Flesh Prison

Equipped creature gets Defender and one +1/+1 counter. At the beginning of your upkeep phase, double the number of +1/+1 counters on equipped creature, up to a maximum of 12 +1/+1 counters.

If equipped creature should be sent to the graveyard by any means, that creature will not be sent to the graveyard; instead, exile Flesh Prison. Equipped creature retains any existing +1/+1 counters and loses Defender.
