From a game design stand point. Both Alolan Ninetales and Hoopa were given Abilities that block all effects of attacks and damage done to it by Pokemon-EX and Pokemon-GX and this is a problem. I understand this was done to give them usage in Expanded but this is where the problem lies. These new Abilities shouldn't target Pokemon-EX because their mechanic isn't in the Sun and Moon meta and would make them too strong in Expanded. This would be like if Safeguard (yes I know older cards won't reference this) targeted Pokemon-GX. I feel Pokemon don't have to do everything and them removing Pokemon-EX from the clause would maintain the balance of Expanded (this isn't saying much) since player would have to pick and choose what to run and prepare for since Hoopa now invalidates all Pokemon with Safeguard. I wish I could say this was an oversight but with the way they have been designing cards, this can't be the case. I know most other, if any Pokemon players will have a problem with this but the fact they are still targeting Pokemon-EX when they have no relevance in Sun and Moon is worrying to me. They could at least give them some more support if they are going to do this. At least some more Mega support.
