Marvo, Deep Operative
Legendary Creature — Octopus Rogue · {3}{U}{B} · Black/Blue commander
Whenever Marvo attacks, clash with defending player. (Each clashing player reveals the top card of their library, then puts that card on their choice of the top or bottom. A player wins if their card had a greater mana value.)
Whenever you win a clash, draw a card. Then you may cast a spell from your hand with mana value 8 or less without paying its mana cost.

What a Marvo, Deep Operative deck wants
The plan the Forge derives for this commander: the roles it fills and how many of each.
- 32× Mana value at or above the floor — for a cascade commander a cheap card is a DEFECT, not a bargain
- 16× A creature that HAS the keyword the commander's trigger counts — a card that merely says the word is not one
- 10× Make creature tokens — a static anthem or a go-wide commander needs a board to be wide
- 5× Actually remove one problem permanent — preventing its damage is not removing it
- 1× Answer a whole board at once
- 2× Answer a spell or ability before it resolves
- 9× Find the exact card the plan needs
- 7× Refill your hand
- 2× Keep a permanent you control alive through removal
