Regarding cards like Spinebiter that say "You may have Spinebiter assign its combat damage as though it weren't blocked.", when/how is that decision made (after you declare attackers, blockers, any point in combat, etc.)? Also, do you literally just say something like "Spinebiter will just deal all its damage to you [the opponent]"? Thanks!
You decide when you’re assigning its combat damage. You just opt whether or not to assign the damage to the player/planeswalker or the creature blocking it.
