It's a quite interesting champ, but in fact, it isn't very good: he depends a lot of his passive, whiches extra abilitiy effects aren't very powerfull, needs that Eidolon die and only works with an enemy champ until his death (what can happen very soon after Eidolon dies).

Anyway, it's only my opinion.
