That tracks. Do you sub Shiva on Takeru? Seems like they would work well together.
The only time I've considered it is for things without wood orbs where belial is functionally useless (and gold keeper, because with both freyr and shiva it's simple to one shot him and the plus eggs help)
Shiva, Freyr, and Takeru on a Suzaku board (with any orb changes) is insanely strong, but complete overkill. And by Complete overkill, I mean, 12 mil overkill. With just freyr I can hit 6 mil regularly on the same (Though, I could consider swapping Freyr for Shiva. The plus eggs might work better, and you don't ever need the 3 turn boost).
Sooo yeah Shiva became useless, 245 + eggs later. Thanks, gungho! I should be used to this, it happens to most of my mains.
Meanwhile, bastet gets reworked at the slightest sign of not being bastet.
