A new card bundle (Explorer Bundle) is available in the store and if you’re looking to spend some money in order to catch up – it’s a solid deal!
For $19.99 (or €19.99) you can buy 20 packs in total – 5x The Witchwood, 5x The Boomsday Project, 5x Rastakhan’s Rumble and 5x Rise of Shadows. Sadly, 3/4 of those expansions will rotate out in 2020, but given that a lot of key cards from those expansions are still played (and they will be in Standard for another ~8 months), you might still consider buying them. On top of that, you’re getting a random Legendary from Saviors of Uldum expansion, and the truth is that SoU has A LOT of powerful Legendaries.
Normally, for $19.99 you can get you 15 packs, which means that the bundle has 33% more value before even counting a random Legendary. It’s not the best deal we’ve ever seen, but still better than buying packs for regular price.
If you’re interested, be sure to grab one quickly, because the promotion lasts only until September 3rd!
