I had to rule on this at my states yesterday. This is the way I ruled it: if you announce an attack you don't have the proper energy for, you may use another attack you do have the energy to use. if not, turn over. Why? 1. In announcing an attack, you have an intention to attack, that must be forfilled. 2. Though pokemon does not have " game phases", it does indeed have steps. Attacking is the LAST step you do. If your intent is to attack, you have intended to enter that step. 3. Allowing a player to " rewind" and preform other actions opens a big can of worms for " gaming". For instance, stalling. You could announce an attack you couldn't do, then, go back and preform other actions, do it again, and take a 10 minute turn. I'm sure most judges would put their foot down at some point, but where would that point be if not clearly defined? And thi clearly defines this. 4. This is rewarding a misplay. Crystal beach is out, and I forget to play my staduim and attack with a H. castform on it,,,,,,,and I get a go back? How about if I forget to attach my energy and attack? I also get to go back? How about it I didn't draw my card, can we go back to the beginning of the turn and start all over? And if I " rewind" to the beginning of the turn, can I play another supporter? why not, after all, if we are going back to the start of the turn, I know it sounds crazy, but if you don't draw a line on this, you can open a can of worms that could produce many " gamemanship" issues.
