Osbourne Highhill, the Fated

As Osbourne enters the battlefield or when a Human or Soldier you control dies, create a Morgenbrew artifact token with "{t}, Sacrifice this artifact: Add {w} or {r}".
Sacrifice a Morgenbrew token: creatures you control gain your choice of first strike, haste, lifelink, or vigilance until end of turn.
{t}, Sacrifice Osbourne: Prevent all combat damage that would be dealt this turn.
