Jeong Jeong's Deserters

The undersized body is the price you pay for the counter it drops on arrival. A 1/2 for two that hands a +1/+1 counter to any creature is really two half-cards stapled together: a mediocre defensive stat line and a growth spell that happens to come attached to a warm body. The design leans on the Ally tag to make that split pay off, since a batch of enters-the-battlefield triggers is worth more the more of them you can chain. On its own the counter is a modest one-shot buff; landed on a creature that also grew from the last one, or on something with an ability keyed to being large, it compounds. The target clause is the flexible part: nothing restricts it to your own creatures, and while few players will want to permanently size up an opponent's threat, the option matters when a counter interacts with something already on the board (soulbond, undying, a proliferate engine) more than it does with combat math. The card supplies no way to grow anything twice from its own text, so the payoff lives entirely in the enter trigger, and the deck around it has to bring either recursion or a wide enough board of small bodies that a stray counter always finds work. Built as a common-rarity engine piece for a go-wide human aggro shell, it asks less about its own stats than about how many times you can make a creature enter.
