This magnificent transmutation centers around Devoted Druid, whose ability to tap for mana and untap by placing a -1/-1 counter on itself normally self-destructs, but is instead sustained and supercharged by the rest of our apparatus. Each time the Druid taps, Leyline of Abundance steps in to double our green mana production, fueling a rich reservoir that eventually lets us activate Leyline's own massive mana sink. When we do, Benevolent Hydra and a fully leveled Innkeeper's Talent act as our true catalysts, multiplying and magnifying every incoming counter so that our creatures grow exponentially rather than incrementally. It is a stunning cycle of growth and renewal, turning a humble druid's self-inflicted burden into boundless strength.
