Ethereal Guidance

The asymmetric +2/+1 anthem is one of white aggression's oldest closing effects, and the sorcery-speed restriction does the load-bearing work of keeping it a curve-topper rather than a combat trick. Granting the bonus only on your own turn means it cannot ambush a blocker or rescue a creature mid-combat; it exists to convert a wide board into lethal during the main phase and nothing else. The +1 toughness is the underrated half of the math: a pure +2/+0 pump risks leaving your team dead to the same blocks it was trying to punch through, so the extra point of toughness keeps attackers alive across trades and lets the board persist into a following turn rather than hollowing itself out on chump blocks. That makes it wider-is-better by construction, scaling linearly with creature count in a way a single oversized swing never does. It belongs to the long line of go-wide overrun effects that ask you to commit a board first and pay off second, the white token-deck answer to the green Overrun template, trading trample for survivability and a lower cost. Nothing here is subtle, and nothing pretends to be flexible: it is a finishing button, waiting on a full board that only needs one more turn to close things out.
