I'm looking for basically a water pokemon with a version of Rising Rivals Trapinch's effect:
"Once during your turn (before your attack), if Trapinch is your Active Pokémon, you may search your discard pile for a basic [Fighting Energy] card and attach it to Trapinch."
Anything like this? Something with an ability where I can return water energies to my hand would work just as well. Especially if it has something similar to 'Grind' where amount of energies determines damage. I have a pretty sweet Manaphy and need something decent to compliment it.
Can't think of a Poke-Power or Attack like that. Nor of one that'll return Water Energy to your hand.
But have you seen Supreme Victors' Milotic C's Aqua Tail attack? Does 10 damage for 1 Energy plus 20 more for each flipped heads for each Water Energy. It's risky, but can be quite fun if you can get a bunch of Water Energy on it. And if you want to save those Water Energies (in case Milotic C may be Knocked Out), you can use Rising Rivals' Lucian's Assignment Supporter card to transfer as many Energy to one Pokemon to another.
EDIT: Just found out about these.
Platinum's Blastoise has a Poke-Power that allows you to look at the top three cards in your Deck once per turn, take any Water Energy, and attach them to any Pokemon any way you like. However, you will have to delete the other cards. So it's risky. This Blastoise does have an attack called Aqua Press, which does 20 damage plus 10 more for each Water Energy in play (on both sides of the field).
Rising Rivals Starmie has a Poke-Power, Aqua Recycle, that allows you to get a Water Energy from your Discard Pile once per turn.
Rising Rivals Snorlax (#33) has a costless attack called Pick and Collect that allows you to get four of any Basic Energy from your Discard Pile and place them in your hand.
Lapras has Grind as well.
If you happen to have Floatzel GL LV.X, its Water Rescue Poke-Body returns any of your Knocked Out Water Pokemon (excluding any Floatzel GL) to your hand instead of your Discard Pile.
