6 Prizes in a Turn? Easy.

Use Earthen Seal Stone (Silver Tempest) to drop all of your opponent's pokemon V to 100 hp, then knock out two using Urshifu VMAX's Rapid Flow attack. If you can get 2 VMAX pokemon this way *cough cough Mew VMAX* then you win! Right then and there! Otherwise, cripple their stratagy as much as possible (Lugia VSTAR? More like, Lugia V was a star!). If you still want to claim 6 prizes as fast as possible try to set up a yoga loop with Medicham to KO another V. Until you can close the game, try to alternate between Urshifu's Gale Thrust attack and Zeraora's Cross Fist attack. 

In case of Manaphy (Brilliant Stars) just use Boss's Orders and Cancelling Cologne.  They won't know what hit them! Just kidding of course... It was a 10 story tall bear.

Thank you, everyone, for deck of the day! Please let me know if you have any feedback!
