The best way is to stop them from swarming the field and using their defensive tactics, the latter of which works if they control two or more "Ice Barriers" monsters; "[[Kaiser Colosseum]]" can prevent this (Traditional onlyOnly) can prevent this. You can also negate their effects, which makes them virtually useless, so cards like "[[Skill Drain]]" and "[[Brotherhood of the Fire Fist - Lion Emperor]]" can work well. You can also prevent "Gantala" from swarming the field by using Special Summon-blocking cards, such as "[[Vanity's Emptiness]]", "[[Archlord Kristya]]", "[[Fossil Dyna Pachycephalo]]", etc.
