Endless Scream
A pure damage-conversion engine dressed up as an Aura, and the design is more elegant than the payoff. The X paid on casting locks in as a permanent block of scream counters, so the entire power boost is front-loaded into a fixed, unchanging number; nothing on the card removes or adds counters after it resolves. That static count is what separates this from a one-shot pump spell: the bonus persists across turns, recurs every combat, and survives summoning sickness wearing off, but it buys exactly zero toughness. The enchanted creature is bigger, never sturdier. The result is an all-offense investment that does nothing to protect itself, and the whole package shares the structural fragility every Aura carries: kill the creature in response or after the fact and the mana sinks with it. The counter framing reads like a hook for future synergy, but the card gives you no way to interact with the counters once they are set, which keeps it honest as a glorified scaling pump rather than an engine. What it offers is a mana sink with no ceiling and a way to turn a small evasive body into a finisher, asking you to weigh a permanent, removal-vulnerable threat against the safer math of holding the same mana for an instant-speed pump when the swing actually matters.
