FYI Pokeflute is not a trainer card, it's an item card. Which means it isn't limited to the same "one per turn" limitation that trainer cards are limited too.

It also means that you can play a trainer card and Pokeflute in the same turn.

That being said, I've used it with great success in both my Lumineon deck, and ever greater success with my Victreebell deck. Had countless games where I knock out the same card 3 times for the win.

I've also seen it used to increase the number of Pokemon on the opponents bench in order to boost Pidgeot EX's attack who gets an attack boost for every Pokemon on the opponents bench.
