Gentravas, Entropy's Scion

During your upkeep, put an entropy counter on Gentravas, Entropy's Scion. Each player searches
their library for X cards, exiles them, then shuffles,
where X is the number of entropy counters on Gentravas.
When Gentravas, Entropy's Scion would go to exile
from anywhere, instead shuffle it into its owner's
library instead.
