Powerstone Collection

when Powerstone collection enters the battlefield
you get an emblem that says: "At the beginning
of each endstep if you control all 5 Powerstone
shards create five 5/5 demon creature tokens with flying."
at the beginning of your draw step instead of
drawing a card you can search your library for a Powerstone card reveal that card and put that
card into your hand then shuffle your library.
