Biomancer's Familiar

The cost-reduction line is a familiar power-level lever wearing a Simic body: shave off every activated ability of a creature you control, then clamp the result so nothing ever falls below one mana. That floor is the entire balancing act. An ability that already costs one mana stays put, so the discount accelerates expensive activations rather than trivializing cheap ones, refusing to hand out the free-loop engines that a true -reduction would unlock. Because it touches every creature you control, this reads as a broad enabler for any board built on tap-abilities and mana sinks, turning sluggish activation costs into something you can fire repeatedly in a turn. The second ability is where the design gets pointed. The tap effect rewrites adapt: aim it at a creature and it adapts as though it had no counters, so a body that already grew is still eligible to adapt, stacking a fresh set of counters on top of the ones it already carries. That pairing is deliberate. The same card that discounts activation costs also refuels the mechanic those costs feed, letting a creature adapt, then adapt again in the same turn for a doubled pile of counters. Two engines share a two-mana frame here: one general cost-reducer for your creatures, and one specific piece of adapt tech that turns the mechanic's one-and-done clause into a repeatable growth spurt.
