Kabutops/Lucario

The idea is simple: Lucario + Kabutops = heal and deal up to 90 damage a turn. With 2 potions you can heal 130 damage in 1 turn. If you get the combo on the field and the opponent can't do enough damage per turn then you just win.

This deck should be able to just bully decks with electric and some dark types, because if Kabutops deals super effective damage it also heals an extra 20 damage. Vs. Pikachu EX you only need 1 Lucario on the bench to out-heal its attack completely, and against Magnezone + Darkrai EX you can heal all the damage they deal each turn with 2x Lucario and 1 potion.
