The problem is…even if you play him on turn 2…you don’t get to attack with him until turn 3. The decks that play treasure cruise heavily are typically made entirely of (creatures, lands, instants, sorceries)..except it’s usually very few creatures. So you’re goyf on turn 3 is usually a 3/4 when it gets in…on turn 3/4 you usually have someone go for a cruise…which can easily shrink your goyf down to a 1/2 or 2/3. He also gets chump blocked all day by YP tokens. One winning deck with him isn’t enough (for me) to say he’s still great..he’s solid against non TC decks…but I really don’t see him doing well in the current metagame..

It’s possible, that demand has dropped for fear of a reprint, but I honestly believe it’s much more to do with the fact that both those cards play terribly with Treasure Cruise (which has drastically shifted both the legacy and modern metagame)
