In the future I feel Ho-Oh will get better. The idea of putting Stage 2 GXs on your bench is pretty crazy, but that limits you to only Pyroar as of now.
Isn't Black Ray GX going to scoop up prize cards if the opponent is unlucky to have lower level pokemon on the bench? It only takes 2 turns to set up. Could take up to 6 cards on the first attack if going first. with a DCE.
I'm an idiot that can't read properlyOnly hits ex's and gx's and there's only one ex that has less than 100 hp
I guess to sum it all up, Ho-oh is an ok card and its GX attack is pretty decent, and Necrozma just wrecks mega ray(although its attack is a one time only thing because we don't have a psychic patch). GX attack is better than Vikavolt's.
Honestly, I am very excited for Marshadow GX(I hope its playable).
