Boast — : Put a lore counter on target Saga you control or remove one from it. (Activate only if this creature attacked this turn and only once each turn.)
Whenever you put a lore counter on a Saga you control, put a +1/+1 counter on up to one other target creature.
Sigurd is a 3-mana Naya beater that turns Sagas into an engine: attack each turn, Boast to add or remove lore counters, and convert every counter placement into a +1/+1 counter on a creature. You build a board of Sagas and creatures, accelerate chapters to retrigger value while pumping your team, then swing wide with buffed, vigilant attackers.
Free repeatable value: Boast lets you control Saga chapters, replaying powerful chapters or rushing to the final one.
Built-in evasion and survivability from vigilance, trample, and lifelink on the commander himself.
Doubles as a +1/+1 counter engine, supporting both Sagas and counters matters synergies.
Naya gives access to elite ramp, removal, and the deepest pool of Sagas across three colors.
Boast requires Sigurd to attack, exposing your commander to removal and combat damage every turn.
Many Sagas sacrifice themselves at their final chapter, so the board can be ephemeral without resets.
Heavily reliant on having Sagas in play; a slow draw leaves Boast and the trigger doing nothing.
Counter and Saga payoffs can be slow, and the deck folds to board wipes and graveyard hate.
Landfall token/counter machine that complements the counters-matter half of the deck.
Add proliferate and counter doublers (Doubling Season, Branching Evolution, Hardened Scales) to multiply both lore and +1/+1 output, and prioritize Sagas whose chapters reward being replayed or stalled via Boast. Improve the mana base with fast rocks and untapped fixing so you can curve into Sigurd by turn three and attack immediately, then close games with a finisher like Craterhoof Behemoth or Cathars' Crusade synergies.
