Rotting Regisaur is a 7/6 trampler for three mana — that's a rate that ends games fast. The discard trigger is a real cost in decks that can't exploit it, but in any shell built around the graveyard or hand-size manipulation, Abigale, Eloquent First-Year and similar commanders turn that drawback into an engine.
Best Commanders
Commanders with the highest synergy
Abigale, Eloquent First-Year
Abigale, Eloquent First-Year rewards large hand sizes, and Rotting Regisaur's forced discard feeds her draw-and-loot loops while keeping the threat on board as an oversized attacker.
Jon Irenicus, Shattered One
Jon Irenicus, Shattered One gifts creatures to opponents, and Rotting Regisaur is a premier donation target — an opponent forced to discard every upkeep is an opponent rapidly losing their grip on the game.
The Gitrog, Ravenous Ride
The Gitrog, Ravenous Ride cares about putting cards in the graveyard, and Rotting Regisaur's discard trigger reliably fuels that engine while threatening lethal damage as a 7/6 trampler.
Xu-Ifit, Osteoharmonist
Xu-Ifit, Osteoharmonist generates value from discarding and cycling through cards, making Rotting Regisaur's upkeep cost a free resource rather than a punishing tax.
Ghoulcaller Gisa
Ghoulcaller Gisa sacrifices Zombies for tokens, and Rotting Regisaur's massive power means a single activation off this creature floods the board with 2/2s — the discard is almost beside the point in that context.

In Commander, Rotting Regisaur earns its slot in any deck that wants to discard — graveyard strategies, madness shells, and donation commanders all turn the drawback into advantage. In Modern and Pioneer, it sees occasional play in Hollow One-style builds where filling the graveyard is the point, though it competes with a crowded three-drop slot. Legacy doesn't need it — the format has faster threats — but it's legal if a specific synergy calls for it. Rotting Regisaur is fundamentally a build-around in constructed and a staple in the right Commander shells; outside those contexts, a vanilla 7/6 that costs you a card every turn is just a liability.
