The Grateful Dead

Indestructible, User: Prosciutto (You may have
two commanders as long as both have either stand or
user. You may not cast this spell unless you control its
user. At the beginning of each end step, if you do not control this creature's user, sacrifice it.)
During your upkeep, you may place an age
counter on any number of non-artifact creatures.
If a creature has 4 or more age counters on it, its controller sacrifices it at the beginning of the
next endstep.
