Gotta load up on Raikou and Zapdos in the case of SBeam, but so far I've avoided fighting one lol
Thankfully w the map over here we know ahead of time what the moves are. All of my own Ho-Ohs so far have Fire Blast lol
Ho-Oh without Solar Beam should be doable with 5 30+ trainers or so, more will be needed if Solar Beam is involved. I think Potions are more common from gyms than stops now, raids give Hyper Potions more often now
