Splinterlands daily quest

My today's splinterlands daily quest was ''Rising Dead - Win 5 ranked battles with the Death Splinter''. It took me a bout 10 battles to finish this quest. When there was under 20 mana to use then I lost, but when above 20 mana I always won because I used Bone Golem and Octopider which both are very mana hungry cards. For my rewards I got 42 DEC and got up about 100 rating.
