Eviolite - Trainer
If this card is attached to a Basic Pokemon, all damage done to this Pokemon is reduced by 20 damage.
You can use any number of Trainer cards during your turn.
So one of the problems in mewgar is mew's low HP of 60. With the new card Eviolite it can help keep mew in the game so it can stay alive longer to keep LZing pokemon and giving you time to build a gengar prime on the bench.
Do you think its worth putting in the deck? Donphan can no longer OHKO it with earthquake.
I personally think it'll do good in the deck. Only problem is finding the eviolite since theres no more Dept store girl or anything.
