Master Chef

Read the wiring before the payoff: this enchantment grants two abilities, and it grants them to your commander, not to your creatures directly. The first clause hands your commander "This creature enters with an additional +1/+1 counter on it," so the general itself lands one size larger. The second hands your commander "Other creatures you control enter with an additional +1/+1 counter on them," an emanating anthem that only functions while the commander is physically on the battlefield. That indirection is the whole design. If your general is anywhere but in play, its anthem for your other creatures does not exist, and everything else you cast arrives at printed size. The bonus keys off the entry event, which makes the effect durable in one direction and fragile in the other: counters placed on arrival stay glued to their creatures through the commander's removal, so a board grown while the general was up does not deflate when it leaves, but the moment the commander is gone, the next wave lands vanilla. Blink, reanimation, and token generation all become ways to bank permanent mass, each conditioned on the commander being present at the instant the creature enters. There is no doubling and no runaway scaling here, only a standing discount on getting big that lives across two permanents: this enchantment and your general. The tax the design collects is a pair of points of failure: keep both Master Chef and the general alive to keep the counters flowing.
