Hello there, I've read your message and I'm here to help. Firstly All the cards that are not from the "TARKIR", "Magic ORIGIONS", or the new "BATTLE FOR ZENDIKAR" block are not considered standard (this way every single card in your deck does not have to be listed). From what I see the only thing standard in your deck are the basic lands,
cancel,
animist's awakening,
opulent palace,
jungle hollow, and
managorger hydra.Sadly if you want a "standard deck you're going to need to
scrap this entire deck except for the cards that I just listed. However, since the entire card set for the three blocks i just listed are on magic the gatherer (the card archive site) then it should be fairly easy for you to
rebuild a new one. This being especially if you invest mostly in the commons and uncommon cards. Tell me, what was the initial focus of this deck?
