If one of my Pokemon was KO'd last turn by damage and Mega Gengar ex's "Shadowy Concealment" Ability kept my opponent from taking a prize for it, will I get to do the bonus damage if I use Krookodile's "Vengeful Fang" attack?
Yes, because your Pokemon was still Knocked Out even if your opponent didn't take a prize card for it.
