A cEDH-style Bant creature-toolbox deck. It runs efficient mana creatures and a deep counterspell and stax suite while using creature tutors and sacrifice-to-search effects to assemble small infinite-mana engines. Derevi is the always-available, flash-speed-adjacent untap source: its tap/untap trigger on entering and on combat damage (doubled by Delney, since Derevi has power 2) untaps mana rocks, dorks, or blockers. Its alternate cost to come straight from the command zone also dodges counterspells. How it wins: The deck generates infinite mana through loops like Kinnan with Basalt Monolith, or a land-untapping Peregrine Drake repeatedly flickered by Eldrazi Displacer, Emiel or Felidar Guardian with Displacer Kitten, then dumps it into Walking Ballista to ping every opponent out. Key roles: - Infinite mana engines: Pieces that loop into unbounded mana, either by doubling mana from a self-untapping artifact or by repeatedly blinking a land-untapping creature, with cost reducers making the flicker activations cheap enough to net mana. (Kinnan, Bonder Prodigy, Basalt Monolith, Peregrine Drake) - Blink and clone package: Repeatable flicker effects, spell-triggered blinking and copy creatures that re-use enter-the-battlefield value or duplicate a combo piece to complete a loop. (Eldrazi Displacer, Displacer Kitten, Spark Double) - Mana sink finisher: Converts limitless mana into lethal damage to any target, with activation discounts sharpening it. (Walking Ballista, Training Grounds, Emiel the Blessed) - Creature tutor chain: Sacrifice-and-search effects and searching creatures dig up exactly the missing combo or utility piece, often putting it straight onto the battlefield. (Birthing Pod, Eldritch Evolution, Ranger-Captain of Eos) - Fast mana and untap acceleration: Cheap dorks, land auras and rocks power out early turns. Derevi, White Plume Adventurer and Delney's trigger doubling untap these mana sources for extra value. (Noble Hierarch, Derevi, Empyrial Tactician, Delney, Streetwise Lookout) - Stax and interaction shell: Dense cheap counterspells and lock pieces shut opponents out during the combo turn or slow their own plans. (Grand Abolisher, Teferi, Time Raveler, Force of Will)
