By rules, I would think this is a fake war.

However, if a KD got waved, and they have a planned war with another, I dont see why they cannot retal the initial wave and jump into the war. Dont think theres a rule saying you cannot retal our wave (therefore eat a wave) just because you are going to a war.

Honestly, AMA should just stop hitting into war and see what Pew does in their war with SWEA. It doesnt help the cause calling people out on fake war when hitting into a war themselves.
