Cheating? For real?

I’ve run into it a few times now, and I double checked for attached items, effects of other Pokémon, attached energy cards and field cards for where the damage was coming from.

Dark Chazard requires your opponent to take prize cards to increase its damage by 30 per prize card taken. So how does a dark Charzard deal 330 damage on the second turn of a match?

How does a regular Charzard who deals 170, and its effect doesn’t enhance damage, but discards 2 energy, deal 340 damage? This is the third turn!

I conceeded the match because it’s clear cheating.
