A-Radha, Coalition Warlord

Domain has almost always cashed out once: a spell that scales its damage, its size, or its cost with the basic land types you control, resolving into a single static payoff. This Radha turns that same counter into a repeatable pump switch, and the trigger condition is what does the work. Tapping is the event, so every attack fuels a +X/+X on another creature you control, while the enter clause means the payoff starts the moment she lands rather than waiting a turn. That reframes domain from a one-shot payment into a targeted engine feeding off a wide, colorful manabase you were already assembling for the fixing itself. The design tension is honest: the bonus never touches Radha, only a single other creature, so she is a spotlight rather than an anthem, pumping one attacker at a time instead of the whole board. Her 3/3 body is small enough that you want the bonus elsewhere anyway. Assemble every basic land type your fixing can reach and a routine swing becomes a lopsided one, but the ceiling exists only if the lands do. She is a build-around whose reward curve tracks how greedy your mana is: a two-color deck gets a modest trick on one creature, a splashy shell gets a swingy bonus it can point wherever the combat math demands.
