Heres the need-to-know on whether or not holding onto that old card collection is worthwhile
This was a moderately efficient burn/swarm deck in that it was fast, but a 3 cost artifact that gave extra draws for 3 just didn't keep up against either Necropotence nor Land Tax card ratios
Mewtwo ex Gardevoir The Mewtwo ex Gardevoir deck relies heavily on a1-129-mewtwo-ex as the main damage dealer, using its early Psychic Sphere as an early damage dealer to threaten to knock out most Pokemon with two attacks
Notable exception: certain Reverse Holos from older or out-of-print sets can fetch significant prices, especially in high grade (PSA 10 / CGC 10)
In comparison, Neave Blacktalon goes for $15, but that card will be much rarer than Squall Leonheart
Honorable Mention #2 (#13 Overall) - Response // Resurgence I run this in many of my Commander decks, more so than the next few
