And thus Sorin totally failed to buff Saber or even Archer, because spur-of-the-moment buffs that feel creepy as fuck because he's mostly linked to Black mana. Not that they honestly need it. XD

Could consider the action to take place simultaneously with their attacks. Board-wide buffs are actually where most of Sorin's White alignment comes from, gameplay-wise. Lifelink as an ability is shared by Black and White.
