I've tried piranas, skeelz and rescue but none of those deck made me any succes.... i got beaten by alot of nightmare decks so i thought that i would try those.... this is my first nightmare deck ever so here it is:
ghumbo + kenny combo had been very usefull. bluff with ghumbo by using like 3 pillz and if they think its not worth using alot of pillz by beat him then i hit them 7 by using only 3 pillz.... and then use rest of the pillz and use fury. that gets me 24 life vs his 2.... and there is almost no chance that they can hit me 23 with his 2 card left.
sure that fails alot of times if they have -dmg ability or stop opp ability.
Personally i find nightmare are better as a half clan. They have no good damage reducers or support cards so it's hard to justify using them mono. They have no way of saving pillz and no way of losing either unless you choose to waste stars on dudley ld or orlok , personally i wouldn't bother with either. Nightmare in a mono are only good for the rounds you win, you need cards that are useful for sapping pillz, saving pillz or reducing damage which is why they don't work well mono. They go well with clans like roots or pussycats because they get dr to compliment them. You could for instance have your nightmare half as azel kenny pan and phyllis then have a roots half of amanie yookie arno and jeena then you have 3 damage reducers 4 soa and the cards compliment eachother as you get life gain and poison going with damage reduction, also you have soa to fend of abilities that may cause you damage. Thats what i would reccomend anyway, good luck
