About Blue Sentinel
Blue Sentinel (Promo) is a promotional printing of Blue Sentinel. It shares collector number 087/219 with the Unleashed original but is a separate product that trades at its own price. It is a Unit in the Mind domain and costs 4 energy to play, with 4 might.
Blue Sentinel is down 16% over the last week, at US$2.18 in the United States today. That is the bottom of its range since 24 Sept 2026 (US$2.18–US$2.90) — the cheapest we have recorded it since 24 Sept 2026. Against a median of US$2.64, it is currently 17% cheap by its own standards.
2 stores in the United States have it in stock, but the pricing is top-heavy: US$2.18 at the cheapest, then a 17675% jump to US$387.50 for the next one. That cheapest listing is doing all the work — if it goes, the effective price of this card rises by roughly 17675% overnight.
Blue Sentinel is stocked in 5 of the markets we track — the United States, the United Kingdom, Singapore, Canada, the EU — each priced in its own currency, so the table above ranks by price inside whichever market you pick rather than converting between them. In the United States the cheapest listing is US$2.18 plus postage at checkout.
The promo print and the base printing are trading at almost the same price right now — US$2.18 against US$2.00 — so the premium version costs effectively nothing extra while that holds.
Priced against the rest of Unleashed, it lands mid-table: dearer than 72% of the set's 336 priced cards, with the set median at US$0.18.

Prices are live listings from stores in each market, in the currency that store actually charges. The “≈ USD” column is an indicative conversion for comparison only — not a quote, and not what you'll be billed. Stores generally ship within their own market, and international postage, duty and GST/VAT aren't included, so a cheaper market elsewhere isn't necessarily cheaper to get delivered to you.
We'll email you when it drops — free, and with an account your watchlist syncs everywhere.
