About Quandrix, the Proof
This page covers the promo pack printing of Quandrix, the Proof (218p), a Blue and Green Legendary Creature — Elder Dragon from Promo Pack: Secrets of Strixhaven (PSOS). It is printed at Mythic Rare rarity. Its text prints Flying, Trample and Cascade. It is legal in Standard, Pioneer, Modern and Legacy and 7 more formats.
We track no other printing of 218p in this set, so there is no base card here to compare its price with.
The cheapest listing we track in the United States is US$1.99, 49% below TCGplayer's US$3.89 market price. Only one store has it in the United States, so the price is whatever that shop asks and there is no second quote to check it against.
The United States is the cheapest of the 2 markets that have it, and the United Kingdom is dearest at about 66% more once converted. In each market's own currency the cheapest listings read US$1.99 in the United States and £2.61 in the United Kingdom. Conversions use indicative exchange rates, and postage, duty and import tax are not included, so a cheaper market elsewhere is a fact about listings and not a reason to import.
Its 90-day high was US$4.15, 6% above today's price.
Promo Pack: Secrets of Strixhaven is a promo pack release, released April 2026. Quandrix, the Proof has 1 other card in the database, listed further down the page.
Flying, trample Cascade (When you cast this spell, exile cards from the top of your library until you exile a nonland card that costs less. You may cast it without paying its mana cost. Put the exiled cards on the bottom in a random order.) Instant and sorcery spells you cast from your hand have cascade.
