There’s a chance this is an outright bug [i.e. these effects *should* trigger], although I really doubt it.
"…with full effect, as if they were matched."
This is not only unambiguous…it tells us twice.
You do not get the full (or partial) effect of banner bonuses “as if they were matched”:
Also, there is no surge effect when matching 3 gems or 5 gems:
I would recommend something along the lines of:
Gems are removed from the board and mana is collected from removed gems.
While this might leave some room for ambiguity regarding banners and surges, it’s no longer false.
