Slith Ascendant

The Slith were Mirrodin's experiment in turning evasion into a growth engine: a tiny body that taxes the opponent for every unanswered hit. The math is the whole proposition. Connect once and it is a 2/2 flier; connect again and it is a 3/3, and so on, each swing compounding the threat it represents. Evasion does the heavy lifting here, because a flier in the early game so often slips past a ground-bound board, and once it lands the first counter the clock only accelerates. The trick is that nothing on the card protects the body, so the design lives entirely in the race between the opponent's removal and your willingness to attack into open mana. Drop it on an empty board and it snowballs; play it into a held burn spell and you have spent three mana on a 1/1 that dies before it ever triggers. That tension is the point: the card rewards aggression and punishes hesitation, asking you to swing while it is still small rather than wait for a safer turn. Among the cycle it sits in white, the color most likely to clear a path for a flier with cheap removal and disruption, which makes it the most reliably aggressive of the five.
