I'm not so familiar with this card
Soul Exchange
Normal Spell
Select 1 monster your opponent controls. This turn, if you would Tribute a monster you control, Tribute the selected monster instead. You cannot conduct your Battle Phase during the turn that you activate this card.
So, this came up today against me... my opponent had no monsters on the field and I had a face-up Ryu Kokki... he activates Soul Exchange and says I have to tribute my Kokki for his tribute set but I argued that he had to have a monster to tribute in the first place... since the effect says "if you would Tribute a monster you control" but he didn't control any monsters when he activated it.
Doesn't the player who activates Soul Exchange have to have a monster that he controls to activate Soul Exchange? Or am I reading too much into it?
