Devlox Holdout

Flying, Entropy 3 (When this creature deals combat
damage to a player, that player searches their library
for three spells, exiles them, then shuffles.)

Moonsynced — When Devlox Holdout attacks,
create a token that's a copy of Devlox Holdout
that's tapped and attacking for each time you've Moonshifted this turn. Exile those tokens at the
end of turn.
