I think invoked has been demoted to a fair level now. Not dead but not oppressive either as they have lost their best possible control partner (Palace + Molehu).
Not sure if Konami would nerf it further but for some reason, I'm sensing that Konami might instead release Magical Meltdown soon.
Same sale tactic like before. Nerf Neos Fusion, release Keeper.
Magical meltdow will not actually solve their current problem. For invoker currently consistency is not the issue. They are strong but in the end of the day invoked is still an engine. What invoked needs now is a new deck they can fit into. this is the reason why we are already seeing Invoked roids and invoked magicain girls.
In theory, 2-3 Magical Meltdown can replace the missing 2 copies of Aleister in the deck. Allowing Elementsaber to use 2 Palace + 1 Aleister.
It's not the same, but yeah, this is just a theory. I dont think it would be as good as straight run 3 Aleister + 3 Palace like before. But that might just be the reason to release Magical Meltdown since it no longer poses a threat.
