Urborg Emissary

The bargain on offer is one of the cleanest reads on what kicker was meant to do: cast it cheaply and you get a fragile 3/1 that wants to race, or commit the extra as you cast and that same enters trigger bounces any permanent on the board. The optionality is gated by color, and that gating is the whole point. The base cost is mono-black, so a black deck never has to apologize for running it, while the upgrade is locked behind blue, nudging toward the Dimir manabase this kind of design was built to encourage. Where later eras gave you split cards and modal spells that defer the choice to resolution, kicker makes you pay for flexibility up front: you commit to the full cost before you cast, not after you see what needs answering. The generosity hides in the targeting. The bounce hits any permanent, not just creatures, so the kicked version can pick off a problem enchantment or reset an opposing land as readily as it clears a blocker. And the two halves of the card pull the same way: a 3/1 that wants to attack profits most from removing whatever is standing in front of it, so the body and the bounce reinforce each other rather than asking you to choose between offense and answer.
