Rathi Assassin

Mercenaries were the era's counter to the Rebel chain, and this is the engine piece that holds the toolbox together: tap to tutor any small Mercenary permanent directly onto the battlefield, then repeat each turn to assemble a board out of a single card. The activated removal is the second half of the design, a gated assassination that only bites tapped nonblack creatures. That restriction does real work: the target has to commit to attacking or tapping out before it becomes vulnerable, and black mirrors are exempt entirely, so this is no Royal Assassin clone that can pick off anything on sight. The asymmetry is deliberate. The Mercenary search climbs only downward in mana value, so the chain pulls cheap utility bodies rather than building toward a bomb, which gives the tribe a grindier, attrition-shaped curve against the upward-tutoring Rebels it was built to contest. The whole package runs on tap symbols, which is the genuine cost: every turn forces a choice between fetching another Mercenary and destroying a creature, and the card cannot do both. Later sets would streamline this two-axis utility creature into cleaner removal-plus-recursion shells, but the Mercenary tutor remains the reason it exists, the card that turns a pile of small permanents into a functioning chain.
