I've just noticed while referencing the book to make sure I'm not saying anything untrue that both greenflame blade and booming blade both use the same "make a melee attack with a weapon" phrasing, so there isn't actually any way to use an unarmed strike with either of them - making my earlier contribution to the thread a lot less practical than I thought it was.
The spell doesn't require the attack be made with the material component.
So you can cast one of these spells while holding a weapon, spell casting focus you are proficient with, or a component pouch in one hand, and attack with a different weapon if that's what you wanted to do.
A weapon being the material component of the spell means that you need to have a weapon (or spell component pouch or spell casting focus you are proficient with, because no specified cost for the component means either of those can replace it) in hand to cast the spell.But the spells material component is (weapon) which an unarmed strike is not, right? Or is that just fluff?
