Wary Farmer

A soft graveyard engine that only turns on when you play to the board: this 3/3 checks at your end step for another creature having entered under your control that turn, and rewards the go-wide sequencing a Kithkin deck wants to do anyway. Deploy a one-drop, drop a token, cast another body, and the incremental filtering falls out of tempo you were already generating. The end-step delay is what pays for it. It does not surveil on cast or on its own arrival; it asks you to keep the creatures coming turn after turn, and it stops working the moment board development stalls. That makes it a barometer for whether an aggressive creature deck is actually functioning rather than a value piece you can strand on an empty table. The filtering it produces is small (one card at a time) but cumulative, and it dovetails with any deck that wants specific cards in the yard: recursion targets, flashback fuel, delirium counting. The mana cost helps it fit either side of its two colors, so a build leaning green or leaning white can run it without straining a manabase. A worker who does its job only while the rest of the crew keeps showing up.
