U have to choose one: play Oath or Landstill.
I agree, I have played both of these decks for decent amounts of time and feel that what you have here is a sub-par version of landstill/oath.
Using the standstill draw engine is a good thing if you are running a deck that functions superiorly underneath is, however this deck lacking in board sweepers will be faced in many situations with not being able to get its draw engine online, because standstill, if played, would benefit the opponent. At that point you hope that oath can save you. However your draw engine is stalled out, and you are in a mad topdeck mode to find answers, find oath, and keep control of the game. EWWW!
Your deck is a jumble of kill conditions and counters that have very little synergy. I would first pick a theme, either landstill or oath. Then rebuild, and retool the deck. After that post again and we can have something to critique.
