Strategy

Curve out ramp into a counter generator, then a Saga. Attack with any counter-bearer to fire Tidus’s Cheer (draw + proliferate, once/turn); proliferate ticks Sagas toward payoff chapters while pumping the whole team. Use Tidus’s begin-combat move plus Nesting Grounds to relocate a lore counter off a Summon: creature-Saga so it dodges its sacrifice chapter and sticks as a permanent that keeps re-triggering (The Duke, Rebel Sentry moves +1/+1 counters and hands out hexproof to protect key carriers). Innkeeper’s Talent doubles every counter placed and hands a free proliferate. Good-Fortune Unicorn, Web-Warriors, and Southern Air Temple blanket the board in +1/+1 counters so there’s always a fresh Tidus target; Drix Fatemaker, Meltstrider Eulogist, Berta, and Synchronized Charge convert the counter pile into pressure and cards. Protect key carriers with shield counters and hexproof tricks (Brokers’ Safeguard, Snakeskin Veil, Spectacular Tactics, Shore Up, Royal Treatment) so the engine never gets blown out, and grind with Tatyova / Enduring Curiosity / Teo card flow plus a lean interaction suite (Stasis Snare, Sheltered by Ghosts, Make Your Move, bounce) to clear blockers and outlast the table.

Upgrade path

NEW BUILD 2026-07-15 — owned-first Brawl conversion of a paper Tidus EDH list (tidus-bant-counters workflow). Keeper mechanics preserved as crafts per Mik: Nesting Grounds (move counters), Innkeeper’s Talent (double counters + proliferate), a shield-counter granter, Karn’s Bastion (proliferate). Commander Tidus is a mythic craft. Doubling Season is the optional mythic upgrade for ‘double counters’. Three cards are unowned and must be crafted, all Mik-requested keepers: Innkeeper’s Talent (rare — the deck’s best counter-doubler + free proliferate, powers both pillars at once), Summon: Fenrir (uncommon creature-Saga Mik named — cheap loop target), and Brokers’ Safeguard (the chosen shield-counter granter to protect attackers; best-fit cheap option from the allowed list). Everything else is owned. The Ozolith and Resourceful Defense were intentionally left out to stay owned-first, since owned The Duke, Rebel Sentry already fills the nonland counter-mover role alongside Tidus and the manabase’s Nesting Grounds. SYNERGY PASS (mined the paper list): +Garnet, Princess of Alexandria (attack = strip lore counters off Sagas banks them as +1/+1s = the Saga-loop PAYOFF), +Evolution Sage / Grateful Apparition / Merfolk Skydiver (proliferate density advances Sagas AND grows team), +Conclave Mentor & owned Growth Curve (counter-doubling). OPTIONAL upgrades: The Ozolith (rare, {1} colorless — the actual card from the paper list; banks counters off dying/leaving creatures and redeploys them, a counter-recursion grind engine), Doubling Season (mythic, doubles counters + tokens), Roaming Throne (rare, trigger-copy). No Arena analog for the paper Devoted Druid infinite-mana line or charge-counter mana rocks.
