Finally managed to get a 6* Masazumi from the advanced dojo and have some how come up with more magas than when I started. All those evolves to get the 6* gave me good maga rewards for evolving/godifying a certain amount of senkai so in a sense this event managed to sustain itself for me. Now I can get even more to improve on her luck or start doing normal events again to level my other senkai.

Yeah that new event is very tough, I only gave the mock battle a go and got owned. I got Nene recently on a money buy with that gacha they had giving away units to complete floor 100 of the advanced dojo, I saw it as not a bad opportunity to get some more 5* units, though you risk getting an event unit with a high lvl luck over bought senkai from it.

I think this new event is like the other creature senkai events and have a feeling this one will come back from time to time...I think.
