Pir, Imaginative Rascal

Counter-doubling is usually a cumulative arms race: each new counter source stacks multiplicatively, the way Doubling Season turns one token into four with a second copy on the field. This design takes the simpler additive route, adding one of each kind of counter on top of whatever the team would already get. That distinction matters more than it reads. The replacement effect fires on every counter-placement event your team controls, not just +1/+1 counters: loyalty, charge, oil, brick, page, any kind at all, each placement gets a flat bonus rather than a percentage. A 1/1 body for three mana with no evasion makes clear the engine, not the creature, is the point. The Partner-with link to Toothy, Imaginary Friend is the rest of the equation: Toothy is the counter sink that turns Pir's extra counters into raw card advantage, and the linked search clause means one half tends to find the other. The pair reads as two cards designed as one closed loop, a self-assembling value engine where the green half inflates the counters and the blue half cashes them in. Pir alone is the modest, reliable component: it does not care how the counters arrive, only that they do, and the plus-one applies to the whole team rather than a single permanent.
