That jirachi could be fun but it really depends on what you're playing, I think ninetales ex isn't so bad too
90 for an ex is rather low but 100 damage for discaring energy is good and it's a stage 1, the other ninetales could be used to stop ex pokémon. Metagrosse ex is good if you can keep him alive, crobat gives grass a big boost, jeesh you don't even have to flip for the poisen, it has also another plus against other grass: it's weak against psychic and not fire, the dominating type at the moment too bad that psychic is the second most seen type. That masquerain is also quit good, no retreat and an attack of 30 for two energies that doubles the damage that is done to the defending pokémon the next turn. I think it's a rather good set.
