Marrow-Gnawertribal_payoff$15.73A Rat tribal payoff that turns your Rat count into a major board presence by making more Rats and giving them fear. It fills the same swarm-scaling role as Swarm of Rats, but at a higher power level.
Ink-Eyes, Servant of Onitribal_creature$7.56A Rat creature in black that scales with combat presence and supports Rat-focused decks through ninjutsu and graveyard value. While not power-per-Rat, it fits the same Rat tribal shell.
Ogre Slumlordtribal_payoffBudget$0.30Not a Rat itself, but it rewards your creatures dying by creating Rat tokens, making it a strong token-swarm payoff for Rat decks. It serves the same go-wide, Rat-themed game plan.
Pack Ratbeater$1.57Another black Rat that scales into a huge threat over time, using excess cards to grow your board. It is one of the closest functional upgrades to a Rat that becomes larger as the game develops.
Rat Colonytribal_beater$5.74A direct Rat tribal beater that scales off the number of Rats you control and in your deck. It is the closest functional analogue to Swarm of Rats for Rat-count scaling.
Relentless Ratstribal_beater$2.60A classic Rat tribal threat that grows with copies of itself, often becoming enormous in dedicated Rat decks. It plays the same swarm-scaling role as Swarm of Rats.
Persistent MarshstalkerbeaterBudget$0.22A black creature that can become a sizable attacker in the late game and fits into grindy monoblack board states. It is not tribal, but it occupies a similar low-cost pressure slot.
Heirloom BladeutilityBudget$0.29This artifact supports creature-tribal decks by refilling threats when one of your creatures dies, helping Rat swarms keep coming. It complements the same tribal swarm strategy rather than replacing the exact body.
