Knights Excelsior

Once per turn, at the start of the combat phase, you can pick 1 friendly KNIGHTS EXCELSIOR PALADIN unit on the battlefield. Until the end of that phase, when you pick that unit to fight, pick 1 enemy unit within 1" of that unit. If the number of models in that enemy unit is greater than the number of models in that PALADIN unit, add 1 to hit and wound rolls for attacks made by that PALADIN unit that target that enemy unit until the end of that turn.
