Vantress Paladin

Adamant asks a deckbuilding question most reward mechanics leave implicit: how mono-colored is your mana actually willing to be? The reward here is small on paper (a +1/+1 counter that turns a 2/2 flyer into a 3/3 flyer), but the design's real function is to price color commitment. A splashed blue creature in a three-color shell casts fine and gets nothing; the same card in a heavy-blue base arrives one step ahead of the curve. That gradient is what the keyword exists to measure. It rewards the player who kept the mana honest without punishing the one who did not, so the card never becomes a dead draw the way a hard color-pip requirement would. Adamant is a soft incentive, not a gate, and this Knight is a clean demonstration of the pattern in its most modest form: a body that flies either way, with a bonus that materializes only when the manabase earns it.
