I have 1 Ho-Oh GX in my Volcanion deck in case I go up against a water deck. The Pokémon Range can be very good to get back to back OHKO on a whole bunch of stuff.
You can us it to shut off Turtonator (built in Bursting Ballon attack he has for 2 energy).
Yes. I had played on line (on my cell phone) and he was using it. It was too small for me to read the text and I couldn't figure out how he was playing a lighting from hand then using the "Strong Charge" from Vikavolt and than changing 1 Lighting to a grass. It works.
Just paralyzed. It's a Heads or Tails attack. If it done both, it would tell you something like : If Tails, do 30 more damage and your opponent's Active Pokémon is now Paralyzed.
Good luck
