This looks like a 5-color Commander good-stuff / midrange deck, with a heavy lean toward black-red and a mix of creature-based value, sacrifice, and swarm pressure.

Primary strategy: The deck appears to win by developing a wide board of creatures—especially Goblins, insects, rats, and other small utility bodies—then grinding value through death triggers, token/sacrifice synergies, and combat pressure. Cards like Virus Beetle, Tunnel Rats, Swarm Culler, Pretending Poxbearers, and various Goblin/Swarm-themed creatures suggest a plan of slowly wearing opponents down while building board presence.

Key synergies:

• Aristocrats-style play: disposable creatures plus cards like Vindictive Warden, Cruel Administrator, and other black value creatures imply payoff for creatures dying or being sacrificed.
• Go-wide aggression: multiple small creatures and tribal-adjacent pieces help flood the board and pressure life totals.
• Value midrange toolbox: the 5-color manabase and many unique legends/utility creatures suggest flexible answers and incremental advantage rather than a single combo finish.
