>>38830111Welder with a natural attachment loads pic related in one turn, or you could use Triple Acceleration Energy if you wanted. The first attack has okay synergy with preparing for Welder.
Sleep is just a random side effect of a few attacks, but there's a Breloom/Amoonguss combo coming in a future set that forces sleep pretty easily. Darkrai Prism and a few other Darkrai cards force double flips for sleep.
Wigglytuff has a pretty good attacker way back in Jungle, but it's only good compared to other attacks within that format.
