It is discarded at the end of the turn
I forgot to read it but it's still a massive nerf. It's reminds me of Stormfront Sableye and the Sabledonk SP Golbat C combo. Golbat SP C's
Flashbite and that SP Tool Arm that takes it back to your hand to re-use
Flashbite upon benching it again and again until the enemy HP is lower. and during Black and White the player going first could attack on turn 1.
Even easier better with Sableye's Overeager Poke-Body, then after benching Golbat as if you had Scoop-Up Net for SP Pokemon and then Sableye's main attack gets boosted from 10 to 40 to kill most types of lowered HP first attacker easily, even those with 100 HP were in danger. It could ruin first turns
Look it up on Celio's Network on youtube.
