The Sphinx Asks

Think of a real Magic card and hold it in your mind. I shall find it — with questions alone.

The black-bordered game is my domain — any set, any era. I do not treat with the silver-bordered Un-cards, nor tokens, stickers, or the digital-only rebalances.

Answer only Yes, No, or Don't know. I allow myself 20 questions — and I do not count the ones you cannot answer.
