You spend 500 gems playing the Gacha card game for 10 packs in the shop any other time. Why not spend that same amount on 20 set cards that you know it is GUARANTEED that you're getting those cards? And yea the Spellcaster one is arguably weaker than the Dragons, but there's still plenty good cards in it. :/
