Thud, Demonic Initiate

Pay 1 life: Exile the top card of target players
library. You may play permanents exiled by
Thud without paying their mana cost, except
they're 1/1 black demon bird creatures in
addition to their other types and they have "when
this creature dies, each player looses 1 life". They
gain haste until end of turn.
At the beginning of the next end step, put all
cards exiled by Thud and cards you control but
don't own on the bottom of their owners libraries
in a random order.
