GRENINJA ex has 2 amazing attacks. For just one energy, "Shinobi Blade" hits for 170 damage and lets you search your deck for any one card. And it's second attack "Mirage Barrage" can hit 2 targets for 120 damage each. Although Greninja ex cannot one hit knock out most high-HP pokemon, FROSLASS really helps to weaken your targets by passively dealing damage counters to pokemon with abilities on them.
