So, I've been using mono sakrohm in ELO and I'm maxing out at about 1100~ but want to achieve 1200 for the 5 credits (1000 clintz)
I've been pretty lucky so far with cards, getting a Murray off Kate in duel.
Well; I want to improve it cheaply, yet efficiently.
Here is the deck:
How much clintz do you have? Does it have to be mono Sakrohm? Cuz for budget ELO decks, imo, one of the best calans are Junkz. You could replace your 5, 4, 3 and a 2* card with Maazk, Fizzle, Treemorh (if you have for him, if not Otakool works nice also) and Flanagan.
About your current deck, I would replace the 4* and 5* first, cheap choices are Mantiz and Eris, a little higher are Jautya and Miss Stella. Also, in a few weeks (or a month, month and a half) Mokra will be cheaper, depends on how cheap, but if you can, buy him then.
As of now; I've got 400 odd clintz - but coincidentally enough, my last duel card was Flanagan.
As far and half decks go - I've tried Sakrohm with Piranas and Skeelz but I didn't feel either of them worked very well.
My highest elo score (1200 something) was with mono Piranhas, but I didn't enjoy playing with them.
Back to Junkz - maybe I could try save up for some to make a half deck, and see how it goes.
As long as you have Murray you can always have a pretty cheap Sakrohm half-deck. You just need a little more options then.
I have a cheap deck building post if you are interested. You can find plenty cheap half-decks there.
