Its first attack, Righteous Blow, causes your opponent to have to discard a Special Energy attached to that Pokemon. With the amount of special energy cards played today, especially Double Colorless Energy, that’s a big deal. It only costs a single Steel energy to use, as well, and deals 30 damage. Its second attack, Steel Bullet, costs 2 Steel energy and 1 colorless and deals 100 damage no matter what.
The only real downside that Cobalion EX has is its weakness to fire, but that’s not the worst problem. It does have 20 points of resistance to Psychic and is bulky at 180 HP. It’s actually one of my favorite Black and White series legendaries along with Kyurem. Cobalon EX also has a full art version in Plasma Storm, as well, so you’ll want to be on the lookout for that.
Cobalion EX is definitely a card I highly recommend for any Pokemon player or collector!
