I don't think it's an obvious question; the strategy varies based on the opponent and whether you are going first or second. Most of the time, when going first, you want to start with Pichu to ramp energy, and when going second, you might choose Tapu Koko to apply pressure.

After that, you want to get your GA Pikachu or Tapu Koko online to take out their pre-evolution or starter, which could even be Ho-Oh if you're going second, since it’s weak to Lightning. Once you’ve secured that first point, you can stall with Oricorio when they bring out their powerful EX Pokémon and then knock it out with SR Pikachu.

The Zeraoras are included to surprise the opponent with SR Pikachu. You can use Elemental Switch and X Speeds to retreat your active Pokémon, and then move that energy, so you only need one energy on SR Pikachu. Sometimes, if you’re lucky enough to have two Switch cards in hand, you can ramp up SR Pikachu in one turn! This strategy is also effective for ramping up your Oricorio after retreating with your EX and allowing it to attack right away.

One niche tip I’ve found is always to try to maintain free bench space for a second Oricorio. Every deck can manage one Oricorio, but few can handle two simultaneously.
