Could say any of these?
Seraph, that's not how a native speaker would say.

Лжедруг looks like an archaic word,
предатель - more like a traitor,
Чистой воды - is set expression meaning 'very true, real' - usually used about things.
Он не лезет с никакими обманами. - grammatically correct, but native speakers wouldn't say that
