I would like to run other decks and i can reach 1300 with almost any but people love very strong ability cards without any defense, the 3 main distribution of decks
1. ability,strong cards rock
2. soa paper
3. anti soa scissors
Of course we have mixes but generally running soa is the best because rock is very popular and mixes always have to sacrifice something, in current game i would say least 80% of the decks are either rock or paper which should make your deck choice quite obvious. Would love to discuss this, obviously deck popularity changes sometimes scissors are the best but it's rare.
A good thing that works vs all those kinds of decks without having too much weaknesses is to to run strong sob cards with strong bonusses or abilitys such as reath or petra. sob decks like piranhas, nearly cripple all bonus based decks while still having a high individual power. Remember that most "paper" have the soa bonus.
sob is one of the most undervalued things in UR cause u can use it as offensive and defensive and it usually beats soa
My advice to any player who feels ELO is a little one-sided is to build a more versatile deck. Run two half-decks that compliment each other, like Rock and Scissors. Facing Paper? Scissors has you covered. Facing Scissors? Rock's got your back. Facing Rock? Well... let's hope you can outplay them with your Rock.
