Old thread, but I just have to post this thing that just happened to me in the online game.
I'm playing Shedinja/Mew EX, my opponent a deck that 'supposedly' has the 'advantage' according to the TCGO. My opponent draws a lone dragon Rayquaza in his starting hand, and I draw 2 Mew EX, an Ultra Ball, Rainbow Energy, 2 Grass Energies and a Professor Sycamore.
I won the coin flip and decide to go first. Draw into DCE, attach to active Mew EX, can't do anything, so I use Ultra Ball, discarding the 2 grass energy and getting Nincada. Opponent's turn, attaches DCE to Rayquaza. Dragon Claw for 30. Draw Frozen City, play it. Attach Rainbow Energy to active Mew. Professor Sycamore into Virizion EX, 2 Repeat Balls, a grass energy, Wally, and some other cards. Can't play Wally this turn, so I'll wait. I use Emerald Slash from Mew, attach 2 grass to Virizion. His turn. He attaches a fire to Rayquaza, then Hard Charm (ehehehe). Uses Pokemon Center Lady, then uses Dragon Claw again. My turn. Evolve Nincada to Shedinja using Wally, Hopeless Scream for 430 damage, game over XD.
