I found out that Harmonia and nomal summon Walbaz can search habakiri and it's making me insane.

Why is walbaz lock only on normal summon?
Why does harmonia locks you from activating effects of anything other than synchro, making superpoly actually work with it?
On a side note, i still find wild how anyone with the extra deck space to run F&V isn't running verte + mirrojade, at least i haven't seen anyone on it.
It's a non target banish that if gotten rid off raigeki the board and searches F&V on the end phase, it's disgusting.
