mtg vivi commander deck Ornitier cEDH Proxy Command the battlefield with this custom 100 Elite Vivi Ornitier Commander Deck

Unbanning an extremely powerful and controversial card like Jace, the Mind Sculptor has the potential to hurt the format as a whole over the long term, which could mean that the short-term gains from selling a lot of Masters 25 will be outweighed by an overall decline in the format if the metagame devolves to Jace decks verses anti-Jace decks

And once it enters, it deals a lot of damage, so you can knock out some creatures, or a creature + planeswalker

Considering the fact that most decks running Hazoret already have shockingly cheap spells and creatures, this was often just a cute bonus

You can end the loop with infinite flying 6/6s with haste by just opting not to put any more lore counters on your Esper Terra clones (it says up to three)

Maybe you want to exile your opponent's blockers so that you can alpha strike for the win
