Hey, looking for some advice, have the opportunity to trade the 151 chase card, pictured below for some of my sealed collection.
Coming in would be the Zard.
Going out would be a Obsidian flames ETB (non pc) and the Morpeka V Union playmat collection (around £50)
At the moment trade value wise seems pretty even, however I’m more concerned about how much the Obsidian Flames ETB will appreciate, let’s say in the next three years. Any thoughts would be greatly appreciated and if I’m in the wrong group for this post if anyone can direct me to the right one.
