Ruling Gengars and legends

[J-chan lll]

so, using this gengar's Hulr Into Darkness http://pokebeach.com/scans/triumphant/94-gengar.jpg

if your opponent has one half of a pokemon legend in his hand, can you discard it?

 

[DNA]

Yeah you can. Each legend half counts as 1 Pokemon when in the hand, and a full set counts as 2. (On that token, you couldn't remove both halves at once with a single {P} energy.)
