You need 2 of these to get the most out of its passive.
The first attack is OK as it can hit the bench, but the second is not... for 4 energy, it could easily have done 80+ to guarantee a 1HKO to stage 1's, or ~100 with discards.
But as it has free retreat (very important on an ex IMO), it explains why the HP and attacks are a little nerfed.
6.5/10 - quite a versatile card to use in any deck.
