new version glitch - cant change deck

I loved the old version, but as soon as I updated to the new version, the deck changed to a low-res, blurry, old-style deck, and in options you can no longer change the deck. The old version was perfect and also seemed faster. How can I go back to the old version? The new update is terrible and needs to be fixed. If it gets fixed, Ill change my rating back to 5 stars
