I find Heatran and Volcanion in a double battle. I know that I have to kill one (and then in catch him later). Which one would you recommend me to catch? Because Volcanion knows explosion!!! 
Get volcaneon now rather than later.
hmm okay but he has explosion, how should I deal with that? I thought about throwing him snore ball or T-wave just to keep him busy hahaha
Have a damp pokemon, although I guess it’s too late. I guess go with heatran since you can’t prepare more
what do you mean with a damp pokemon?
A pokemon with the damp ability, which makes it so pokemon can’t self destruct or explode
my team is D. Charizard/Thundurus/Mew/Lucario/Feraligatr/Charizard
ah okay, I think I dont have anyone of with that ability, so I think I should take Heatran and then Volcanion…
I caught Volcanion at the end. He just get paraz all time and doing Hydro Pump, Overheat and Body Slam… So lucky!
