Discard leftovers with Bang Boom Electrode, and get them back again with Snorlax! The other tools let you reach a little further if needed.
This deck really struggles to keep bench space open. An ideal board state can look like:
A Voltorb/Electrode in the active.
1. Voltorb/Electrode to ready another attacker
2. Snorlax
3. Miraidon ex
4. Rotom V/Rotom VMAX
5. Another Snorlax/Honchcrow V
If you don't start with a loaded bench, Miriadon EX helps setup quickly at the cost of a bench space. Otherwise, if you can get away without benching the Miraidon ex then you have a little more breathing room for Snorlax, Rotom V/Vmax, and Honchcrow.
When facing some single-prize decks, the Honchcrow V may not be needed.
Rotom V's ability is a wonderful way to end turn 1 going first. However putting it down later in the game would be more ideal.
