I thought this was a pretty good idea, especially if you can't get to more than one League session to get caught up. However, I saw room for improvement. Here's what I came up with:

Ok, here's how it works. Start by getting out Blaine's Magmar (duh!) and throw a few energy on him (you're bound to get three energy in the first three turns.) Keep Berry/Gold Berry on him to keep him alive. When you only have one B. Magmar out, use Good Manners or Pokémon March to get your other two out. Use Sabrina's Gaze when you've got tons of Energy in your hand that you want for your Lava Burst attack and also want your Trainers. Trash Exchange is helpful when you're running low on Energy in your deck and only have Trainers in there, thus not doing much damage.

If you've got them, I suggest putting in Gold Berry and Potion. I took out the Blaine Trainer because it's rare, and I turned this into an Uncommon deck.
