That would be a good idea . Hot swap a battery . Not sure why they would lose capacity due to aIt having a plug . <| sep |> Here are the results ! So i took MalyDruid , Shaman mid and N ' zoth Warrior , the tournament was a 16 participant double elimination with a winner ' s BO 3 loser ' s bracket BO 1 1 lost on the first round playing my druid against a beast druid , and then my warrior against against his miracle rogue he had an incredible draw i lost both matches . Then i went on the loser ' s bracket and won 4 matches in a row with my n ' zoth warrior , i finally lost against a freez mage I had 4 hp , he had 1 hp and one card , he toped deck his last ice block , i play n ' zoth i had no defensive card , then he top decked a frostball ping and that was the end of it .
