Glacierwood Siege I suspect many players will play Glacierwood Siege to get more Crucible of Worlds action going on, but this card can be a strong mill option as well
Important cards with this mechanic are Grim Flayer and Ishkanah, Grafwidow
Korvold, Fae-Cursed King As one of the most popular Commanders ever, Korvold more than deserves his spot here, even with how much his sacrifice-based powers can sting
However, if you like the archetype, this card is a possible inclusion in 1v1 formats
If a player is attacked and doesnt have any creatures on the field to block with, or any special cards in their hand to defend themselves with, they subtract the attacking creatures power from their life total
Its also graveyard hate that also stabilizes you with life gain or pushes the last points of damage on your opponents, and one of the best shamans in the game in case its creature type is relevant in your deck
