Harvestrite Host

Every Rabbit that walks onto the battlefield hands a creature +1/+0, and nothing caps how many times it fires: flood the board and you flood the pumps. What splits the incentive is the second clause, which pays a card only on the second resolution of the ability each turn, no more and no fewer. The pump feeds any creature you control, so the aggression it enables is not tribally locked; the refill is, since only Rabbits (and the Host itself) advance you toward that second entry. So the aggressive turn and the card-drawing turn are not always the same turn. A wide dump does the most raw damage; a steadier stream of small Rabbit permanents serves the draw clause more reliably, because it guarantees the second entry rather than burying the payoff under a single explosive cast while a threat is worth pumping. That gap is the building problem the design poses. Most white aggro payoffs want the biggest possible turn and stop there; this one wants you to sequence for two things at once, hitting exactly the second entry while a creature still profits from the boost. Land that reliably and every additional Rabbit past the second is pure pressure stacked on top of a refueled hand.
