Unstable Amulet

Two engines that normally sit in separate decks get bolted together here, and the seam is where the card gets interesting. The tap ability spends two energy to impulse-draw the top card and lets you play it on your own schedule, which turns around and satisfies the middle clause: a Pyromancer-style ping that fires not on instants and sorceries but on any spell cast from a zone other than your hand. Impulse-draw, flashback, adventure, foretell, and every other cast-from-elsewhere line becomes incidental damage to each opponent. The energy is what meters the loop. The entering trigger hands you exactly one activation; everything after has to be paid for by other energy sources, so a deck built around the counter gets a rolling advantage machine while a splash gets a single dig and a dead artifact. The two clauses feed each other in a tight circle: the impulse draw generates the cast-from-exile trigger, the trigger burns the opponent, and the more of your gameplan lives outside your hand, the harder the circle turns. It reads less like a value rock and more like a small combustion chamber, converting cast-from-nonhand triggers into face damage while it supplies the cards that generate those triggers. Energy, usually a closed loop that generates and spends inside one archetype, here becomes the fuel gauge on a reach-and-card-advantage engine.
