Sifter Wurm

A 7/7 trampler for seven mana is the kind of green body that has needed no justification since the earliest sets, but the enters trigger here is doing something tidier than a flat lifegain rider. The two effects fire in a deliberate order: scry 3 first, so you arrange the top of your library exactly how you want it, then the reveal pays you life equal to the mana value of whatever you chose to leave there. The gain is not a fixed number stapled to the body; it is a function of your own deckbuilding. A deck full of cheap spells reliably leaves a one or a two on top after the scry, while a top-heavy shell can park a fat payoff there and bank a sizable cushion before the wurm ever swings. What makes this cleaner than most green fatties of this size is that the design hands you the variance and the tool to manage it in the same breath: scry 3 is not just card selection, it is the dial that sets how much life the reveal returns. The body still does what a 7/7 trampler does. The trigger is a self-contained reward for knowing, and shaping, what sits on top of your deck.
