I am a level 16 and quite new to this game.
I have 400 clintz and 19 credits from rewards. I am making a skeelz deck and have these following cards.
Hugo , Timber , Vansaar , Sol Hona , Cley , Danae , Deebler , Drake , Zeke , Sandro ,Otto , Greem (my most favourite in my collection)
You've pretty decent cards towards making a Skeelz deck already. So assuming we keep it T1 (25 stars), I suggest buying Redra and assembling:
Redra, Cley, Greem, Sandro, Otto, Danae, Drake/Zeke (pick who works best for you), and Hugo.
Must-haves for mono-Skeelz decks are Redra, Sasha, Sandro and Chiara so which of 'em you don't have are pretty good targets when deciding who to get next.
Also, good luck with your next pack as your credits are so close to 20
you haven't stated what type of deck you want to build i.e. normal T1, T2, ELO, DM T1, DM T2, Survivor T1 or Survivor T2
Anyways, here is my take on it ...
Cley, Danae, Deebler, Drake, Zeke, Sandro, Otto, Greem = 24*
your current skeelz (that you have mentioned here) make a pretty good deck (not a big fan of Drake though, personally)
you can replace Drake with Hugo (26*)
You are missing out on the staple ELO cards of the clan (such as Chiara, Redra & Praxie) and with the amount of clintz & credits you have right now, I'd suggest either getting Redra now or get yourself another credit (through mission rewards, DTs, etc) and try your luck in the "New Blood" pack. If all goes well, you can obtain some of the high-priced new cards and sell them at the market for an amount to puchase Chiara & Praxie.
A decent mono Skeelz ELO deck would be:
Zeke, Danae, Redra, Chiara, Praxie, Liam, Greem/Jay, Tomas/Aylen
note: As stated before, this is my personal take on it and critics shouldn't post here in order to contradict me rather it should be to help this guy/gal out
GL ad GG ... always
My advice would be to get a credit from playing in a daily tournament. After that, wait until the next release of new cards and buy a new blood pack. Hopefully from this you will get something good, sell whatever you get straightaway. After that my advice would be to buy chiara. She is a must-have skeelz card. With any leftovers, i'd buy a staple card such as redra / tomas or if your short of clintz, eloxia or dwan.
Now comes the deck making. If your looking for a type 1 or ELO deck i'd play:
otto (or sasha)
Deebler (or chiara)
