(As a Siege enters, choose an opponent to protect it. You and others can attack it. When it's defeated, exile it, then cast it transformed.)
When this Siege enters, choose one or both —
• Destroy all legendary creatures.
• Destroy all nonlegendary creatures.
Menace, deathtouch
Whenever Marchesa attacks, remove all counters from up to one target permanent.
At the beginning of your upkeep, if you haven't been dealt combat damage since your last turn, you draw a card and you lose 1 life.
Cast Invasion of Fiora as a one-sided-ish board wipe (choose to destroy legendaries and/or nonlegendaries), then defeat the battle to flip it into Marchesa, a menacing deathtouch attacker who pulls counters and draws you extra cards. You play a midrange/control game in mono-black, clearing boards repeatedly and grinding card advantage while attacking unblocked thanks to evasion and a king-of-the-hill removal package.
Add fast mana (Sol Ring, Mana Vault, Crypt) and elite tutors (Demonic Tutor, Vampiric Tutor, Diabolic Intent) to assemble Marchesa or wipes on schedule. Lean into a legendary-heavy creature base so your own 'destroy all nonlegendary' mode is one-sided, and include lifegain (Whip of Erebos, Bontu's Monument) to fuel life-payment draw engines. Top-end can shift toward a Bolas's Citadel + life-loss combo for a deterministic kill.
