Gorxos, Bleeding Nightmare

Flying, Blood Pact (Whenever a creature with
Blood Pact enters the battlefield, creatures you control
with Blood Pact get +1/+0 until end of turn and you
lose 1 life.)
When Gorxos, Bleeding Nightmare enters the
battlefield, Reroll Fate.
If your fate is greater than 4, creatures you
control have Blood Pact. (Multiple instances of
Blood Pact on the same creature do nothing.)
