the best thing about this Kagero is how the spell doesn't need target anymore as the follower dmg effect is random, so opponent can't play around it by setting up little to no board it's frankly insane how the spell only costs 1pp while being better in almost every regards but the LW requirement (which is moot due to trees anyway) than the old counterpart, but that's powercreep for you
kagero feels like viscera but much better because you can play him early for the LW effect and get the payoff later when you need the damage. he's both the engine and payoff
