Strategy:

Lucario is the main attacker able to quickly do spread damage to the opponent. Also, the deck relies on using Lucario Lv. X’s Stance pokepower a lot via Premier Ball.

Swampert GE is in the deck to move energy as needed.

Swampert ex CG is a secondary attacker and its pokepower Energy Recycle coupled with Stance can be an excellent way to do energy acceleration.

Claydol allows you to draw more cards, which is always a good thing.

Unown G is used solely for its Guard pokepower.

Can this deck stand up in today's metagame (Blissey, Mags, G&G, etc...)? What changes would make this deck better?
