Sanctified Charge

The split here is the whole design. A team-wide pump that hands +2/+1 to everything but reserves first strike for the white creatures rewards a board that has stayed mono-white without punishing a stray off-color body too harshly: the green or black creature you splashed still gets the stats, it just doesn't pick up the keyword. That conditional second clause is what nudges this toward a white weenie shell rather than a generic go-wide trick, and it changes the combat math more than the raw +2/+1 suggests. First strike on a board of small attackers means the defender can no longer trade up by blocking; chump or eat the damage, but the blocker dies before it swings back. As a finisher it asks for a developed board to convert into lethal, and the instant timing lets it sit until the attack step or ambush a planeswalker's would-be protectors. White aggro has leaned on effects like this across eras under different names, but the white-creatures-only rider is this version's particular wrinkle: a small reward for building disciplined rather than greedy, drawing a line in the sand between the mono-white team and the splash you couldn't resist.
