God-Pharoahs gift bug

MISTERMOIST

The support is supposed to return the last creature card from your graveyard to play with the zombie subtype and haste, and exile it at end of turn.  It does this properly, unless you have a copy of that creature in play already. For example I was using the support with sovereign flagship(only creature in deck) and gather the pack.  I summoned a flagship before I was able to draw gather the pack(finally did draw and cast).  I had the support in play, flagship on battlefield and at the start of my next turn it summoned another flagship and it did give it the zombie subtype but it just reinforced my already existing flagship(which also gained a zombie subtype), however it was not exiled at end of turn(it did not get haste either, this point is kinda moot since it was already in play, it is just for details sake). It's a handy bug if I stack my deck with only the flagship and destroy or discard spells with God-pharoahs gift, lol, however a bug nonetheless  .
