Do you have enough damage in your Freaks deck? In Freaks decks that is usually the biggest flaw. The poison is important and can compensate for low damage at times, but KOing the opponent is just as important in a Freaks deck as it is in a lot of other decks.
Granted, players can use Freaks for life gaps (especially with some cards like Twyh and Wolfgang), and that's fine, but if that's not working out I seriously suggest you try adding more damage to your deck and see how it helps you fight.
I will try to use that suggestion I hope it will be helpful But the problem is the nightmare deck I hate them. If This doesn't work I will gone buy nightmare deck!!!!
