At the beginning of your end step, if you have fewer than eight cards in hand, draw cards equal to the difference.
Doctor Octopus is a Dimir Villains-tribal commander that keeps your grip stocked to eight cards every turn, turning that overflowing hand into card advantage you can convert into board presence and disruption. Deploy Villains to benefit from the +2/+2 anthem while you durdle behind interaction, then close with a wide tribal swing, a big spell, or an unfair combo fueled by your refilling hand. Early game you stall and develop; mid-to-late game your draw engine snowballs uncontested.
Built-in, no-strings card advantage that refills you to eight every end step
Anthem effect pumps a Villain tribal board for fast clocks
Blue-black gives the best interaction, removal, and tutors in the format
Hand refill synergizes with wheel, discard-outlet, and reanimation strategies
Hard to run out of gas in long, grindy games
Seven mana and no immediate board impact makes him slow and easy to ignore until late
Villain typeline is narrow, limiting genuine tribal payoffs in non-Marvel pools
No evasion or protection built in—removal-heavy tables can keep him off the board
Drawing into a full hand does nothing if you can't deploy threats fast enough
Vulnerable to graveyard hate and counterspells when leaning on combo finishes
