Your list looks reasonable on a budget , but has a couple weak spots . Here is what I would do to improve it without using Epics or Legendaries . Fireblaze Obelysk Rare is one of the strongest Dervishrelated cards in the game . I would include 3 of them as a priority . To make room , I would suggest removing both Bloodletters and 1 more minion or spell of your choice . Bloodletter is a super weak card , as a 46 body or ' 8 ' 6 against a general , with extra scaling from buffs is extremely small for a 6 drop . For comparison , a vanilla 6 drop Stormmetal Golem is an 88 . Considering the fact that Bloodletter has no effect to make up for this , other than the extra damage to a general , I ' d say the Bloodletters are your first priority of cards to cut . I would try to have more 3 ofs and fewer 2 ofs , so that your deck is more consistent . For instance , if you have three 2 ofs , you can entirely remove a 2 of and instead have two 3 ofs My wording might be confusing here . Sorry ! . That ' s not to say that 2 ofs are bad , especially in a game with the Replace mechanic , but you have quite a lot of them . For the above point , which cards you choose to remove are mostly up to you it depends on which parts of your deck are giving you the most success . From my perspective , I would suggest the War Talons or Dominate Wills besides the Bloodletters , which in my opinion should be the first things you remove , or the Cosmic Flesh , but probably not all of those cards at once . Without Aymara Healer , your lategame and survivability power is limited , but there are likely better choices than those . I would consider at least a third Starfire Scarab . The reason I suggest removing the War Talons and Dominate Wills is that having four 7 mana cards in your deck might be too much , as you could end up having too many dead cards for most of the game , or you might be overrun by aggro before you have a chance to play them . Windstorm Obelysk is an okay card , but has some antisynergy with Dervishes when you ' re trying to hit a general with a bunch of them , because they usually don ' t die after hitting the general as they have 3 , not 2 HP , meaning they clog up space around the general . I would consider cutting these , but only if you have Fireblaze Obelysks . I would include 23 x Whisper of the Sands Common , depending on how often you have Obelysks stick . It ' s a great tool for burst damage or removal , and it even spawns Dervishes around dispelled Obelysks . I would replace your copies of Siphon Energy with Ephemeral Shrouds . They ' re slightly lower tempo , but the reach on the dispel is really useful . I only suggest this because of the Siphon Energy nerf . With those changes , I think your deck would be significantly improved !
