Witness of Tomorrows

A five-mana 3/4 flyer whose activation costs four more mana to scry once is a plain rate any way you slice it, and that activation reads as a late-game mana sink rather than an engine anyone actually leans on. The real work happens in the type line: this Sphinx is an enchantment and a creature at once, filling two boxes for any mechanic that counts card types. It enters as a single permanent, so it feeds a constellation trigger exactly once like any other enchantment; where it earns its slot is as a body that also counts toward delirium, survives inside enchantment-matters shells, and keeps flying blockers honest long after any enters-the-battlefield value is spent. Outside a card-type shell, it is a common flyer that fills a curve and smooths draws when nothing better is happening. Inside one, the front of the card was never asked to carry a deck on stats; it exists to be a resilient permanent that pulls double duty on the battlefield's bookkeeping, a flyer whose value is measured in how many "counts as an enchantment" and "counts as a creature" ledgers it shows up on rather than in the numbers it prints.
