Sieg, the Summoner

Whenever you sacrifice a non-token creature,
summon a token with lifelink and "all creature
your opponent control loses lifelink". If you
already control one, summon a token with
flying and "all creature your opponent control
loses flying". Repeat this process for hexproof
and indestructible.
Sacrifice a token with lifelink, a token with flying,
with hexproof and a token with indestructible:
summon Artiom, primal predator a legendary 5/5
with lifelink, indestructible, flying and
hexpr
