Lutri, the Spellchaser is the only one card that is specifically banned as companion in Commander , since every singleton format already adheres to Lutri's requirement, so it'd be the most stapled, auto-included card alongside Izzet commanders
One of the mistake I made with the old monster reviews was trying to tell too much of the stories which made me exhausted when I go to the cards, and there are a lot of better youtube videos and Wiki articles that explain things better and with pictures and novel excerpts
As is, the removal in Standard is so good that relying on untapping with Etali, Primal Storm on the battlefield is unreliable at best, and you need to untap with this six-drop unless you can give it haste to make playing it worthwhile
Overall it is too slow, gold and unreliable to merit inclusion in the main cube but it is a cute card
When picking up cards for speculative purposes, though, I dont like to acquire the big cards for hopes of gains in the same timeframe
