The card-draw trigger here is built on a cost most spellslinger payoffs never charge: tapping two of your own creatures. That converts an already-tapped-out board into dead triggers and rewards a wide battlefield over a lean control shell, which is why the anthem ability earns its keep. Every spell asks whether the extra card is worth committing two bodies for a turn, so the draw is never free the way a plain "draw on cast" trigger would be; the tension is between spending your creatures as engine fuel and holding them back to guard the board. The vigilance rider does subtler work than it first reads: a creature with vigilance attacks without tapping, so it can swing in combat and then still be tapped after damage to pay for the card-draw trigger. The same body attacks and fuels the engine in one turn instead of choosing between the two, which justifies committing five mana to the anthem. The result is an engine that scales with creature count rather than raw spell density, pushing deckbuilding toward creature-heavy tempo instead of pure instant-and-sorcery piles. On a 1/3 body, it blocks well enough to survive to the point where the engine turns on, then becomes a mana sink once the game stalls. It belongs to a line of white-blue commanders that refuse to let the creature half or the spell half of a deck coast on the other.
