my best donk is kingdra double donk this was in a CC too
against magmar active and magmar bench: Sure I had weakness on the active but the 70 hp on the bench was a big issue. I started horsea, baltoy, uxie, water energy, rare candy, crobat G, googley
I start with horsea active with an energy, then put down baltoy, crobat, and uxie. Doing ten to the bench and drawing five cards. I top out a scoop, a turn, plus power, Bts, and kingdra. Drop the plus, turn for ten more to bench, and fail the scoop. Play the BTS, rare candy to Kingdra, and googley for an uxie and energy. I drop the uxie for my last bench space. I draw into claydol, energy, kingdra, poke turn, SSU, and a second SSU. I miss one SSU then drop the bat again with the turn putting the bench down to 40 HP, hit the second SSU for another ten. Finally I use the claydol I put down a water energy and the kingdra. Drew into a pokedex handy, ssu, baltoy, BTS, and another water energy. My best bet is to land the SSU, but I miss it. Lastly I top out a poketurn with the pokedex handy and use it for the last ten needed. Finally I use dragon pump to do 100 to the active and 20 to the bench for double knocks.
