Gamble is red's only real tutor.
Legacy and Commander demand. Not sure if Vintage cares here, except perhaps in a mono-red combo deck.
This is about to spike and then settle to a likely $50.
Reprint is not impossible. If reprinted today, even at mythic, this would be toppled down to $5, or $10 at best. I am keeping a single copy for play purposes and hoping to sell any specs into the coming spike, hopefully above $50. Without a reprint this could see $100 in a few years (Grim Tutor, anyone?)
Find some copies around $25. No Foils available.
Compare the graph before the spike, back in early 2014, with the graph right now: it's very self-similar, the main difference is that we're moving at a larger scale now.
The first spike took us from $10 to a healthy $20. This time we're going from $25 to a healthy $50. We've also got more upward trajectory heading into the spike, so these may well be conservative speculations.
This is no gamble.
