2 zapdosEX is optimal but the reality is that ZapdosEX is primarily a wall (especially against fighting types) and just works better than most other walls by virtue of having a 1 cost attack and 1 retreat. You're only using the coinflip as a last resort, when you've repeatedly misplayed or been screwed on draws. Sub-optimal walls are Baby Zapdos (for retreat cost and "I fucked up" last resort attack) or Kangaskhan (for poke-damage while setting up). Kanga is much more likely to die rather than be switched out though plus it loses the fighting-defense aspect.
On another note it's better to cut to one Pinurchin if possible, opting for a second wall, and cut Red Card for the Surge.
My hottest take is to cut one Sabrina for a second potion. PikaEX+Raichu inherently doesn't rely on Sabrina as much as other decks, your opponent will play around it, and you'll only ever use one Sabrina per game if you're in a winning position. There's also the factor of Surge competing for your supporter-for-turn when it really matters.I may not be an ex-professional tcg player, but I have been playing primarily variations of PikaEX since launch and my winrate hovers at around 75%.
