I plan on #HODL the CL packs for at least 3-6 months . The price has been dropping a lot. Are you using the low end summoners ? which league are you getting to with those? The idea I had with building out the deck was focus on two splinters. I focused on the Fire and Water. Then I researched some summoners . I selected the monsters based on their attack (Melee, Magic or Range) . I'm finding out that I need monsters with more health and faster speed. I get killed in battle if someone select all Magic monsters.
