I doubt the "Special War Powers" refer to an entire organization, if it did, it would most certainly include the Royal Guard. Yhwach had the Gotei on the ropes and retreated, more or less due to the risk of their appearance.

I would assume Yhwach might have at least two unknown War Powers on his side. So here's my list. 1. Ichigo Kurosaki 2. Zaraki Kenpachi 3. Haschwalth (seems like he would be one, seems pretty strong) 4. Unnamed Quincy of some sort ~ A unrevealed character. Or Ishida. 5. Inoue Orihime.
