Raging Bolt uses Origin Palkia VSTAR, Sandy Shocks ex, and Sada's Vitality as support to swarm the field with energy cards. Having 3 different Ancient Pokemon can let you utilize Sada to attach more and deal more damage.
I used to run 3 Sandy Shocks ex, but I found that 2 is a solid number and replaced one with a Slither Wing to help make games "7-prize games".
Possible tech options could be to swap out 2 energy for 2 Grass energy, and swap out something for Iron Leaves ex to make the Charizard matchup a bit easier. Another option could be Maximum Belt to help hit OHKOs on stage 2 exs and anything with Hero's Cape.
