Leyline of the Mountains

Red spells and nonmana abilities of red permanents have Assist (Another player can
pay any amount of the spell’s or ability's generic mana cost).

Whenever a player pays for a spell or ability they don’t control, that player may deal 2 damage to any target. If they do, exile all other abilities of Leylines.

"It's ironic that we grind up the mountains to make these circuits and boards when they already have a kind of intelligence. A soul, too."
