I'm guessing you don't know how to properly defend yourself in ranked PvP.
There are shields for every school attack, universal tower shields that work against all attacks, damage reduction spells like weakness and absorb and even spells that cause attacks to fail completely like dispels. All the tools to survive in pvp are there for you to use, but you chose not to learn them and instead complain about treasure cards.
You are you're own problem right now. There are ways to counter everything in pvp, the difference is some people learn how to do it and others just reach for something to blame their loss on (in this case treasure cards)
Keep practicing, think about how you lost after a match and add cards to deck that can help or prevent it from happening. Also take out cards that you don't need and use your sideboard to your advantage.
