Things to concider
if you are concidering parmabarb (who only works up till danger zone) I4d also put in taljion (danger zone)
surstroming is amazing
raskal is great but would stick with ironjaw
all others that you mentioned will do fine
Amiral Coco is over hyped IMO. Dr Alma is a good turn 2 play and gets the most use out of turn 3. IronJaw certainly is good but I'd pick Dalhia Cr over him any day. If money is an issue then IronJaw still helps. Langren vs Ursula, well Ursula is a winning round kind of girl in the later rounds and Langren is a turn 3 loss followed by round 1 and 2 wins. Or a turn 2 loss to block damage in the event you need to. I would drop Amiral Coco and add in both Ursula and Langren.
-Does GHEIST goes well with Piranas? Got some good GHEIST cards here... Same Roots bonus.
-Don't have any LD Piranas =/
-Does Hive goes well in ELO? cause its bonus is star related.
-Dropping Amiral Coco and adding Ursula and Langren consume a lot of stars, considering using IronJaw in the deck too. Resulting in 4432 (Ursula, Langren, IronJaw and Parmabarb). The other half would be 2244 or 2334. Personally, i like using 1 5*.
