Tui and La, Moon and Ocean

Gameplan

Tui and La is a mono-blue value engine that rewards repeatedly tapping and untapping your commander—each tap draws a card and each untap grows it. You assemble cheap tappers (convoke, crew, mana abilities), untappers, and vigilance/blink effects to loop the trigger every turn while sculpting your hand, then close with a swollen, evasive attacker or a card-advantage-fueled control finish.

Key Cards

• Thousand-Year Elixir — Lets you tap the commander for its ability the turn it enters and adds an extra untap each turn.
• Intruder Alarm — Untaps your tapped creatures whenever a creature enters, enabling repeated untap triggers and counters.
• Kiora's Follower — Untaps Tui and La on demand to bank a +1/+1 counter and reset it for another tap.
• Seedborn Muse — Untaps the commander every untap step, triggering both draw setups and counter growth across the table.
• Vigilance — Effects granting vigilance let it attack and stay up to keep tapping for cards via convoke or mana abilities.
• Thassa, Deep-Dwelling — Blinks the commander to untap it for a counter and provides repeatable scry plus board protection.
• Cyclonic Rift — The premier mono-blue blowout to clear the way for your evasive, counter-loaded commander to close.

Upgrade Path

Add reliable untap loops—Intruder Alarm with cheap creatures, Seedborn Muse, or Aphetto Alchemist plus mana rocks—to convert draws into mana and counters, then layer protection like Lightning Greaves, Heroic Intervention effects, and counterspells to keep the engine online. Tighten the mana base with fast rocks (Sol Ring, Mana Crypt) and add a clean combo or alt-win (Thassa's Oracle with a self-mill enabler, or Aetherflux Reservoir) so your card advantage actually closes games rather than just spinning your wheels.
