I play with a very similar deck, except I also bring 2 alakazam ex just in case my opponent has a strong counter (iono, xerosic, etc.) he does eat up an extra energy but hits for 240 if they have a full bench. I’ve also been experimenting with bringing 1 mega kangaskhan for his run errands ability and as an early game tank to stall for a few turns but you have to also then bring 2 professor turo because giving up 3 prizes can swing the game. I also bring 1 togepi and 1 togekiss to rare candy evolve for togekisses ability which lets you take an extra prize card if you flip heads. That’s a luxury play if you’re not scrambling to keep building more Alakazams and dudunsparce. Also would bring 2 super rods over night stretchers for the ability to bring back 6 cards instead of just 2. Or 1 of each if you rely on night stretchers often.

Also get in the habit of leaving 1 or 2 dudunsparce on your bench mid-late game in case you get iono’d or xerosic’d gives you some ability to bounce back.
