Whenever Garnet attacks, you may remove a lore counter from each of any number of Sagas you control. Put a +1/+1 counter on Garnet for each lore counter removed this way.
Garnet is a value-voltron engine built around Sagas. Deploy cheap GW Sagas, then attack with Garnet to peel a lore counter off each one—growing her with a pile of +1/+1 counters while resetting your Sagas so you can re-trigger their early, powerful chapters with proliferate. You close on lifelink-fueled commander damage while the Saga engine generates board presence and card advantage every turn.
Doubles as a token/value engine and a Voltron threat in one two-mana body
Lifelink stabilizes you while attacking and snowballs huge life totals
Reusing Saga chapters dodges the usual 'Sagas are one-and-done' drawback
Counters synergy stacks explosively with doublers and proliferate
Low mana value makes recasting after removal cheap and forgiving
Heavily reliant on having Sagas already in play to grow Garnet meaningfully
Vulnerable to single-target removal and pump effects do nothing if she dies
Sagas naturally sacrifice on their final chapter unless you reset them
Counter wipes and 'destroy all creatures' hose your whole plan
Copies your best Saga, multiplying the lore counters Garnet can harvest.
Add more proliferate (Flux Channeler, Evolution Sage) and counter doublers (Vorinclex, Monstrous Raider) to maximize each combat, and lean on premium Sagas with valuable early chapters worth re-triggering. Include protection like Heroic Intervention, Swiftfoot Boots, and Teferi's Protection so a single removal spell doesn't reset your engine. Finish with a haymaker—Craterhoof Behemoth or Triumph of the Hordes—to convert your wide, counter-laden board into a one-shot kill.
