It's been almost two weeks since the release of the Wailing Caverns Mini-Set and the patch 20.4 alongside it on June 3 - so a couple of dust refund options are nearing their expiration date. No better time for that last search of your collection to see if there is anything still hiding in there. Soon the following cards will no longer grant you the full amount of arcane dust upon disenchanting: 

There should still be over 24 hours left to decide and pull that trigger. Possibly even slightly longer than that if the last few cases are anything to go by - but better not postpone anything until you forget or the opportunity goes away.

If you were still planning on buying or opening any packs from the relevant expansions (Ashes of Outland for Hand of A'dal or Scholomance Academy for First Day of School), best get to it. You might just hit any of the above Commons as your duplicates; maybe even find a Golden version. 

Perhaps you also went on a spree of collecting some of these special Standard packs that have recently arrived with the patch in question, in which case we suggest double checking if you might have pulled either of these cards.

If you are unsure, the best advice is to always disenchant the affected cards and then recraft afterwards if they prove to be necessary for the decks you wish to play. You don't lose out on anything in that scenario, and may eventually get them back from any of the packs mentioned above. 

For what it's worth, Paladin is not doing too hot right now - some would place it near the bottom of the power rankings, together with Mage and maybe Warlock. First Day of School saw its second change within the course of a month, as we were having a similar reminder about it just a few weeks ago. But this time it is a proper, direct nerf. Hand of A'dal hasn't lost as much of its power, yet these two hits along with the new Wailing Caverns cards not offering anything potent for the class was enough to topple one of the meta kings.

Quote From Blizzard
The cards listed above will be eligible for a full dust refund for 2 weeks after the 20.4 patch goes live.

Do we have any stalwart Paladin believers who are still trying to put up a fight despite everything?
