In a meta with little combo, would this be a playable deck at the moment?

16x Snow-Covered Plains
4x Scrying Sheets
1x Mouth of Ronom
1x Kor Haven

3x Decree of Justice
3x Eternal Dragon
1x Sacred Mesa

3x Enlightened Tutor
3x Sensei's Divining Top

3x Orim's Chant
3x Abeyance

4x StP
1x Austere Command
3x Wing Shards
3x Wrath of God

3x Isochron Scepter
1x Powder Keg
1x Seal of Cleansing
1x Story Circle
1x Moat
1x Oblivion Ring


I yet have to figure out the Sb. This deck hasn't been discussed for pretty long, is it outdated, or are there new cards that should be in there? Would this be a good list at the moment?
