I just wanna asked help for those who play splinterlands, I can't understand this quest, I need to accomplish one to claim the loot chest however I already tried everything just to make it full and I follow the details to include sniper monsters on my deck and win, however the quest didn't get full and I can't claim the chest. Do I need to use all sniper monster in one battle? Here's the screenshot of the quest guys.❤❤
