Maybe it would've been better if it was ' when the lightning pokemon this card is attached to attacks, it also does 10 damage to each of your opponents benched pokemon'?
Maybe up the ante with instead 'when the lightning pokemon this card is attached to attacks it does 10 damage to each pokemon in play both yours and your opponents pokemon excluding any lightning pokemon (don't apply weakness and resistance to this damage). '
Fire special should be 'Burn energy'' - If the fire pokemon this card is attached to receives any damage from your opponents pokemon, the attacking pokemon is now burned.
Water special should be 'Life energy' - Remove 1 damage counter between turns from the water pokemon this card is attached to.
