Take out Porah and Haaken, Swap Leopold for Graven or Fiddler, then you have 2 Stars remaining to use as you please.
Take out Porah and Tormentah replace with Stompah/ 4 Star LD Frozen, and also take out Leopold and replace Granny May/Pedro with Fiddler/Graven, or alternatively for the Berzerk side, take out Leopold and Miloz and bring in a 4 Star Berzerk, like Kommando Ld/Silvano.
Definitely cut it down to 8 cards with the following star formats I recommend
Both fairly common deck set ups
4+4+4+3+3+3+2+2-(personal favorite format)- good for consistent balanced hands
5+5+5+2+2+2+2+2-Gamble it may give you an awesome 3 5* hand or a 4 2*hand and anything in between
The main issue I find is this deck don't have synergy the only attack plan I can see with this is lose try again raise and repeat until you win a match.
Miloz make for too much revenge cards and you need better heavy hitters right now your best hitter has the life gap of 12 IF all the conditions are met
Meaning you need 9 or less life, lost the last round, fury and not blocked by any form of manipulation or protection at all and then survive any additional rounds. Making Tormentah both overly risky and predictable to rely in for that gap. Odds are that 12 gap will almost never hit.
Mahimatah is also your only true defence card, but -1 dmg is not going to cut it for revenge cards so I would recommend the common staple of lola or Tiwi LD for a 3 * spot, if neither of them I recommend Silvano or ruru or at the very least Snorkar.
I just find your deck too aggressive with little to support it and will need to consume mass quantities of pills to win rounds you need either pill manipulation, more atk manipulation to conserve your pills and reduce their's or defensive cards to pad out the rounds to launch revenge attacks.
I have to disagree with @anzboy when it comes to star distribution!
I'd personally suggest something like 4/3/3/3/2/2/2 (22*) and focus on just winning rounds. A 25* deck like @anzboy suggested will ONLY work for a good DT placement if you're an amazing player with like 90+% winrate or you KO very quick: both things I doubt you can do with a deck like the one you showed (no offense, it's not like I can get 90% either, mine usually stay around 80-85% in DT).
So ye, I would avoid doing stars like @anzboy suggested in DT, except for the 5/5/5/2x5 option, that one seems not too bad, maybe it'll work well I can't know for sure.
