Invasion of Fiora // Marchesa, Resolute Monarch is a six-mana wrath that kills all legendary creatures, all non-legendary creatures, or both — then flips into a recurring removal engine that takes over the late game. The cost is steep and the legendary clause can hurt you as much as opponents, but the floor is still a one-sided-ish sweeper and the ceiling is a permanent that draws cards and eliminates threats every turn; Cleopatra, Exiled Pharaoh lists understand this immediately.
Best Commanders
Commanders with the highest synergy
Cleopatra, Exiled Pharaoh
Cleopatra, Exiled Pharaoh's ability to generate value from powerful, expensive spells makes Invasion of Fiora // Marchesa, Resolute Monarch a natural fit — the battle clears the board while Cleopatra's engine recoupes the card disadvantage, and flipping into Marchesa gives the deck a recurring, game-closing threat.
Shanid, Sleepers' Scourge
Shanid, Sleepers' Scourge draws a card whenever you play a legendary permanent or spell, so Invasion of Fiora // Marchesa, Resolute Monarch is doing double duty: it's a board wipe on cast and it draws from Shanid before it even resolves, with Marchesa as a legendary payoff waiting on the other side.
Glissa Sunslayer
Glissa Sunslayer already wants to hold up interaction and punish opponents' boards, so Invasion of Fiora // Marchesa, Resolute Monarch slots cleanly into that gameplan — clear the non-legendary threats Glissa can't profitably block into, then let Marchesa generate the incremental advantage Glissa decks are built around.

Commander is where Invasion of Fiora // Marchesa, Resolute Monarch does its best work — multiplayer tables are full of legendary commanders and non-legendary value creatures, so the battle's modal wrath hits exactly what you need it to hit, and Marchesa's triggered ability generates real card and board advantage in long games. In Pioneer and Modern the six-mana cost is prohibitive; there are cheaper, more reliable sweepers at those speeds, and the payoff of flipping into Marchesa is too slow to matter before the game ends. Legacy and Vintage have the same problem compounded — six mana is essentially unplayable in those formats. Stick to Commander and Oathbreaker, where the late-game power of both halves actually comes online.
