Menace
When Siegfried enters, mill three cards. Then put X +1/+1 counters on Siegfried, where X is twice the number of creature cards in your graveyard.
Siegfried is a mono-black voltron beater that snowballs out of your graveyard: mill creatures, then stack twice as many counters on him to swing for huge menace damage. Spend the early game self-milling and ramping, drop Siegfried as a one-card threat that's already enormous off a fat creature-heavy yard, then protect him and connect for lethal commander damage in two or three swings.
Add fast mana (Dark Ritual, Sol Ring) and tutors (Demonic Tutor, Stoneforge Mystic) to assemble protective equipment faster. Lean harder into self-mill (Hermit Druid, Mesmeric Orb) so Siegfried enters at lethal size, and pack instant-speed protection (Heroic Intervention substitute Malakir Rebirth, Apostle's Blessing) plus reanimation to insure against board wipes. Cut clunky vanilla creatures for low-cost evasion enablers and graveyard payoffs that win even when Siegfried is answered.
