Alseid of Lifes Bounty and Hateful Eidolon were strong enough to spawn a successful deck in Pioneer, and with the addition of Lurrus of the Dream-Den, you have an efficient and powerful bogles deck one which attempts to build up one or two ultra-powerful creatures using auras and then protect them as they win over a couple of turns
It does nothing if you cant stick creatures in play, which is usually enough to just pass altogether
But do the new cards solve any issues in Commander
As for gameplay, Venom lets you sacrifice cards to draw and play other spells, potentially shifting your board state pretty quickly
That said, the card is unreal and definitely a pillar of Standard with crossformat applications
That said, until we have a proper dino sac deck, and we never will, this stays in the bulk bins
