Terrorborne Ibete

Menace
When Terrorborne Ibete enters the battlefield,
target opponent searches your library for three
non-land cards, exiles those cards, then you shuffle.
That player chooses one of those exiled cards. Terrorborne Ibete gains Entropy X, where X is the
chosen card's casting cost. (When this creature deals
combat damage to a player, that player searches their library for X cards, exiles them, then shuffles.)
