In Commander it gives red decks and Boros decks significantly more protection from flooding out, and in the lands matters decks like Windgrace and The Gitrog Monster, it will do a ton of work
Tribute 1 monster from your hand or field, or send 1 monster from your Extra Deck to the GY, also after that, Ritual Summon any number of "Nekroz" monsters whose total Levels equal the Level of that monster
From past releases, cards like Command Tower, Command Beacon, and Blade of Selves have been among the most expensive in the set
I think we can all agree we want more of them
It remains to be seen whether this is worth losing access to all of the cascade support that includes green, but hes still definitely a powerful commander
The impression is that the cost is pinpoint, so the habit seems to be a little strong
