I am more excited about the Amazing Rares than the Lovecraftian Eternatus VMAX.
I love new game mechanics and gimmicks.
There’s definitely more to the Amazing Rare than what’s posted so far. Otherwise, Celebi and the other Legendaries would have Pound/Tackle attacks to offset the “negative prize” effect.
I have feeling that they will be limited to one-per deck. At least, that would give them a shot at having some semblance of interesting/good attacks and Abilities.
And unlike Prism Stars, I think these could/should be back from discard pile. Part of why the Prism Star cards didn’t do well outside of Ditto was that almost all of them were awkward to use because of the Lost Zone rule or just too gimmicky for their own good.
That said, if they can be brought back from the discard pile, control decks just gained a bunch of “pseudo Dolls”
