Nick Fury, the Assembler

When Nick Fury, the Assembler enters or leaves
the battlefield, search your library for a creature
card. Reveal it and put it into your hand. Shuffle
your library.

When Nick Fury leaves the battlefield, exile it with
3 times counters on it. It gains suspend. (At the beginning of your upkeep remove a time counter.
When the last is removed, cast Nick Fury without
paying its mana cost.)
