Strategy to Stop a Ghisiki Perfection Deck

I was curious if anyone had any strategies or combinations against a Ghisiki Ritual based deck.

Not really just keep their rituals away

The 3 Gishki aquamirrors are their key cards.If you can banish those 3 mirrors most gishki decks actually cant ritual summon.Depends on what deck you run but monster effects that remove cards from play are common.Mirror of the ice barrier may help too.Another thing is that all gishki monsters are water attribute monsters.. putting a Catastor in your extra should solve the problem.
