For the roots / nightmare, why mawpin? artus and phyllis, are IMO, a little better, artus is a different kind of card and phyllis I find to be a little more reliable
rico may be a little better than noodile, until 5 pillz at least, which is more than the usual amount you would use on a 4 damage card, of course there are exceptions, like keeping pillz to counter spyke etc. But overall I usually find a little atk manipulation more helpful.
for the gheist / vortex deck, indeed I find dagg better as a 4 star than dregn is for a 5 star, especially against all this soa
for the gheist / nightmare, I'm more of a kenny guy instead of azel, but it all has to do with play style and personal prefference, overall it looks pretty competitive. Also some players prefer xu52 instead of wardom, but it's also a matter of play style
for the sentine l/ gheist, lehane is banned now and will also be banned next week. Personally I'm not a huge fan of 3 star damage reducers, but there are exceptions like bristone, uranus and lola, otherwise I prefer my dmg reduction at 2 stars and a more powerful 3 star. Maybe morgan for lehane and flynch for melvin, if there is a massive SOA presence... but overall I don't find it very attractive
from the 4 decks, the gheist / nightmare is the strongest IMO
I decided to go with Soa/Sob line it proved to be extremely reliable, vortex don't really like soa and won't play senti without lehane
Roots / Nightmare
Artus - i already had 2 damage reducers more is just trouble, rico x artus < mawpin x yookie imo
Phyllis - She is nice on her own but bad synergy with the staples of the deck like azel, she gretchen and azel are are what i call initiator cards, having gretchen and azel could lead to problems already , also Azel Gretchen Pan could already play against dr cards, if you play kenny then you can play her but i'd rather keep her out since she is a terrible finisher
Mawpin - Having a single revenge ability is really not hard to trigger
Rico - Obviously against soa he is worse and even against most cards they need the same pillz, with +1-2 attack and rico would be the the king
Kenny - Don't like him that much too many variables, vs high dmg clan he is pretty bad, ability soa kills him , leviathon , any dr card , power manipulation not his favourite either, big poison cards really don't mind it if you play him. Apart from this he is crazy 9/15 gap is devastating at any time fury is almost a must with him and also don't mind insane amount of pillz. Against damage lacking decks 1 round of kenny could win it all.
I would add jeena as an awesome 3* dr card, better then bristone
Well i am really tired now but ill rerun my options later for sure
