Yet Invoked has pretty much been anywhere from Tier 1-3 ever since it was first released 1 year and 2 months ago. They've hit it multiple times with restrictions, and none have been enough to knock it out of the meta. The only way to actually do some real damage against Invoked is to restrict Aleister, and they've had more than a year to do it.
Look at TCG forbidden list and you will know that Konami can do anything. They can just outright ban this card at 0. Nothing is impossible, just be prepared.
Invoked Elemensabers, Invoked Neos, Invoked Magician Girls, Invoked Roids, Invoked Neos... You can just put this card in every single deck. Banning this card can stop all kind of abuses.
