But its great in Commander too, appearing in almost 100,000 decks on EDHRec
"Turbofog" decks are decks that rely on a number of cards that prevent combat damage (such as Fog) or kill numerous creatures at once (such as Wrath of God) along with card-drawing effect to stall the game long enough to set up some sort of mana-intensive win condition, usually a combo (or by stalling the game long enough that the opponent decks themselves)
There are still a few more things to consider though, like extras and bonus cards that arent actually playable as part of the game
Shell probably sit well in a Gonti deck of either persuasion, but Gonti Canny Aquistor will appreciate it more
Beyond introducing powerful reprints like my personal favourite, Rise of the Dark Realms the game also introduces a raft of strong new Equipment cards, more removal spells, and cards that provide great reward for slinging spells
Whenever you roll Chaos, return target permanent card from your graveyard to the battlefield
