Forum:Lilith + lair of darkness

So say my opponent has Lilith,_Lady_of_Lament and Lair_of_Darkness on the field. On my turn let's say I summon Ultimate_Conductor_Tyranno and my opponent activates Lilith,_Lady_of_Lament's effect to tribute my monster. Can I chain ultimate conductor tyranno's effect to chain, I choose to destroy itself.

My opponent says that I can't chain because lilth's effect is a cost so UCT is technically isn't on the field even though UCT's effect is a cost too.
