Cateran Summons

For a single black mana, this fetches any Mercenary directly to hand, and it is the engine card that anchors the tribe's identity. Mercenaries worked as a downward-chaining toolbox: each one could tutor a smaller Mercenary into play, so the deck assembled itself as a stack of creatures with a clear top and bottom. The problem the tribe faced was getting the right piece into the chain at the right moment, and that is precisely the gap this fills. It does not produce a body (the activated abilities already do that work); it reaches past mana value to grab whatever the situation demands and books it for next turn, which makes it a deckbuilding multiplier rather than a tempo play. Compare the structural job to a colorless artifact tutor: the cost is trivial, the search is unrestricted within the tribe, and the only friction is the sorcery timing and the shuffle, both of which keep it as a setup spell rather than a reactive one. The card is also a reminder of how cleanly the Mercenary mechanic was designed around tutoring: a one-mana sorcery this generous only exists because the entire tribe was built to be assembled instead of cast, and a card that finds any piece is exactly what a chain-based archetype needs to stop relying on raw draws.
