Summoner's Sending

Graveyard hate is usually a sorcery-speed shrug or a one-shot exile, but here the payoff is baked into the removal itself: every creature card you strip from a graveyard hands you a flyer, and a big enough exile hands you a slightly bigger one. That coupling is the whole design logic. It turns a maintenance effect (chipping away at reanimator targets, delve fuel, recursion loops) into a slow token engine that also happens to build a board. The end-step timing is doing quiet work: because the trigger is free and passive, there is no cost to holding it, so it simply waits for graveyards to fill before it skims the best target off the top each turn. The reward, though, is strictly binary. Exile anything with mana value 3 or less and you get a 1/1 Spirit; clear the four-mana line and it arrives as a 2/2. That threshold points squarely at expensive reanimation payoffs: the Griselbrand-sized threats that flood a graveyard clear the bar and give you the upgraded body, so the same trigger that denies the biggest thing pays out its better token for denying it. It asks nothing of you beyond patience and a table with things worth exiling, which is why the card behaves less like a hate piece and more like a white attrition engine wearing hate-piece clothing.
