I have golden Raid the Sky Temple. It's been months trying to make it work in a deck, but they simply can't win consistently. Should I disenchant it or wait for the next expansion? It's worth 1600 dust though.
personally raid the sky temple is actually sort of made redundant by reno from galak awakens
no requirement no mana requirement no quest requirement meaning your top decks to find early solutions to boards are easier
reno the hero card casts a random spell not just in mage per turn for 0 mana of course it's not as targetted but the plus side is you can spend 10 mana instead of always being on 8 with the -2 discount... BUT wait u get it back no u can't use ALEXtrasa and other nine drops at the same turn which some decks need
just explaining the mechanics and also however issues with it and yeah i still wouldn't disenchant it cuz i have heaps of gold and dust i'm not sure what everyone's situation is i keep all my wild cards and i'm a wild player so up to u
I know that even No-minion Mage decks which were popular in early April quickly cut the card as the value it creates is very dubious given random is significantly worse than discover. There is a very slight chance that Blizzard might decide to actually change it (buff it) to become 'Discover a Mage Spell' (without the discount), in which case it will probably become a very good card. So I'd say keep it for now
I use it in my mage deck which is all around discovering and randomly generating things as well as a load of secrets. I fully accept that it isn't a competitive card or deck but due to star bonuses I can still climb to diamond with it. Personally I think its a super fun card and I've comfortably used this mage deck than any other deck since I started playing, which was somewhere around KoFT.
If you don't want to mess about with less competitive decks though and you need a legendary or several cards for a different, more ladder climbing friendly deck, then seeing as it's golden it may well be worth the dust. Maybe worth just hanging fire until the cards for next months expansion are revealed, just on the off chance that mage gets some cards that make that sort of deck more competitive. I doubt it but we're so late into this cycle now that unless you're desperately wanting to craft something, it's probably worth at least holding fire for a few weeks.
