[Fate]

I would not be opposed to a weaker dom summon (like summon 20). If you buffed the temple guard back up to their original stats, they would be worth it (and available by mid-game). It would slow down the early game a tad maybe, but not much as Itza has plenty of other excellent recruits.

Another option that I believe I mentioned already (as I like it) is to have Slann battle-summon 2-5 guards. I think this is quite thematic (the guards following the Slann) but it might also be a little unbalanced (assassinations would be harder, though they are already difficult, and it would be more feasible to tele-drop Slann on enemy PD). Maybe battle-summon 3 and domsummon 20?
