The Ozolith
The Ozolith
Whenever a creature you control leaves the battlefield, if it had counters on it, put those counters on The Ozolith.
At the beginning of combat on your turn, if The Ozolith has counters on it, you may move all counters from The Ozolith onto target creature.
As it twists, so does all life around it.

I mean you could use those as a snake factory if you're so inclined, but I think that's far from being Commander combo of the set.
