Enclave Cryptologist

A 0/1 for one mana that never grows past 0/1 no matter how much you invest in it: every level counter buys upgrades to its activated ability instead of its body, which tells you exactly what this Merfolk is for. It does not block, it does not race, it parks behind the line and turns surplus mana into card flow. At the first two levels it is a Merfolk Looter in different clothes: tap to draw and discard, filtering one card a turn so long as you have something worth pitching. Reach the top tier and the discard clause falls away, graduating the filter into clean, repeatable card advantage that answers to nothing but your own removal-free survival. The cost of that graduation is the whole balancing act. Each level counter runs , and three are needed to unlock the unconditional draw, so the engine demands six mana past the casting cost, paid in pieces at sorcery speed across several turns, with the body never improving to defend the sunk investment. A one-drop that draws a free card every turn would be an absurd rate, so the counters function as a tempo tax collected up front, before the payoff ever arrives. A single removal spell at any rung along the climb refunds none of what you have poured in, which is the price the card pays for promising raw card advantage off a one-mana commitment.
