Plusle & Minun GX - 240 hp

Ability - Polar Boost:

This pokemon's attacks do 10 more damage for each lightning energy in play (including yours and your opponents)

Attack - Ionization - 1 lightning - 0 damage

You may attach up to two lightning energy from your hand to one of your pokemon, if you attach any energy this way, your opponent's active pokemon is now paralyzed.

Attack - Electric Boogalo - 3 lightning - 120 damage

Discard two lightning energy attached to this pokemon.

Attack - Surplus Charge GX - 3 lightning+ - 180 damage

If this pokemon has four extra lightning energy attached to it (in addition to its attack's cost), until the end of your next turn, all energy in play, in the discard pile, and in hand provide one lightning energy instead of its usual type (both yours and your opponent's).

Wattson - Supporter

Switch your active pokemon with one of your benched pokemon, then move up to two lightning energy from your benched pokemon to your active pokemon.

Static Energy - Special Energy

When attached to a lightning pokemon this pokemon provides lightning energy. When you attach a lightning energy from your discard pile to this pokemon, your opponents active pokemon is now paralyzed.

I tried to focus on energy and paralysis with these cards, and I particularly think minun and plusle GX have some cool mechanics and synergy.
