A-Sunbathing Rootwalla

The Rootwalla lineage was built on a fixed, repeatable pump: pay a little mana, get a small burst, do it again next turn. This rebalanced digital variant keeps that once-per-turn cadence but hands the size of the boost to domain, the mechanic that counts basic land types across your battlefield. That swaps a flat, predictable increment for a scaling one whose ceiling is set by how far your manabase reaches. A two-color deck gets a modest bump; a deck that reaches across the whole color pie turns the same activation into a threat that grows out of removal range. The elegant part is that domain is powered by the lands you already want: shocklands, typed dual taplands, and triomes each carry multiple basic land types, so widening the color spread and feeding the pump are the same act rather than competing ones. The "A-" prefix marks this as the Arena-only rebalance, distinct from the paper card whose numbers Wizards judged out of line. The 2/2 body for is intentionally forgettable on its own; all of the card's upside is gated behind a deckbuilding commitment to lands that count for domain, and the pump only cashes out if you actually assemble that spread. It is a study in how domain converts a flat combat trick into a variable one, with the manabase, not the mana cost, doing the pricing.
