Fblthp, Totally Not Lost...!?

Protection from Artifacts. Whenever Fblthp enters a zone, reveal it and lose 1 life. If Fblthp would be discarded from your hand, instead discard into exile.
If Fblthp is revealed at least four times from the same zone, you win the game.
{4}{u}: Put Fblthp on top of your Library, then shuffle your Library. Activate only if Fblthp is exiled.
(The existing zones are the Library, Hand, Battlefield, Graveyard and Exile)
