Theres a reason why WotC and R&D avoid regeneration effects and powerful hexproof creatures, so Id expect totem aura effects to only be present in supplementary sets in the future
You can spend 3 mana to blink your entire board once, but spend 5 and theyll blink twice
Tribal strategies are well supported in Commander, and do well as creature strategies that can develop a wide board early, which Jazal incentivizes
They reprinted Exquisite Blood in a Commander precon (technically it was in Jumpstart (2020) and added to The List that same year, those are not reliable ways to obtain a copy and are a clear reason why Bloodthirsty Conqueror is a chase card from Foundations )
The decklist provided uses Geist of Saint Traft as a reliable early-game hexproof threat that piles on damage with a toolbox of equipment for different situations
This set is surprisingly packed with interesting, powerful, and even just fun designs, given how parasitic the mechanics are (shrines, lessons, allies, etc.)
