When you have a option to disable a challenger's card, target ones with the most arrows indicating the most spaces. This will certainly avoid your challenger from using that card in addition to block combos from those directions unless they restore or get rid of that card. When your challenger begins a combo, reduce the effects of up the card they will certainly most likely to use as the last one in that chain.
