Tips and Tricks
Start off each one of your battles by filling up the arena with as many monsters as you can.
You can only put monsters in the tiles adjacent to where your hero is, so move your hero around so that you can summon monsters to instantly attack opposing characters.
Don’t spend your Rubicoins on the base level chest. Save up your coins so that you can spend them on better chests, which contain better cards.
You earn more than enough free cards between winning battles that you can very easily fill up your deck.
Always have more than one type of fighter in your deck in order to maximize your advantage against all types of opposing decks.
