Sphinx's Insight

Addendum is an ability word built to reward the tempo player for acting on their own terms, and this is the plainest illustration of what that reward looks like. The base spell is a straightforward two-card refill; the rider layers a small life gain on top when you fire it off proactively rather than holding it up on an opponent's turn. The tension is genuine, if small: the card is marginally better when cast as a sorcery, but a control shell wants to keep it as instant-speed insurance against an empty grip late in the game, forgoing the two life to preserve that flexibility. The design question is exactly this trade: is the modest life buffer worth surrendering the reactive window a two-color draw spell would otherwise want? On the low end of that scale, the payoff is small enough that most decks treat the life as a freebie rather than a real decision, which is intentional. This sits at the accessible edge of the mechanic, where the incentive nudges without ever punishing. It reads as a workhorse card-advantage spell for a color pair that has always priced its raw draw carefully, with a bonus that costs nothing to earn when you were casting on your own turn anyway.
