This is an amazing game with a massive world play witch is free at first but gives you multiple paid options for future play as well. It is 75% strategy and skill and 25% luck. The strategy portion of the game is from choosing items, what is equipped, battle strategy, what school/element to focus on, and how to build your deck. The luck side of this game is drawing cards from your deck, random item and chest spawns, and what your opponent does.
