I've been following this thread closely since August (pg. 133 or so) and finally took the leap into legacy with Elves! in October. Before then, I was just a casual EDH player. I'm pretty aware of the bad matchups (UW CounterTop, fast combo, etc.) and wanted to gauge how to improve my deck the most without breaking the bank. My current decklist (all cards owned) is in the link below:

I threw the sideboard together on a budget so there is definitely room for improvement there. Some things in the deck I'd obviously like to change are:
1. Splashing black for DRS, Cabal Therapy, and Abrupt Decay
2. Using Craterhoof Behemoth/Mirror Entity as my win-con
3. Maybe trying Natural Order (similar to LSV's list)
4. Add Scavenging Ooze to the SB to deal with reanimator

Which of these would increase the power level of my deck the most? Also, how much worse is NO when there is a lot of counter-magic in the meta? Is it worse than having a Crop Rotation countered? The 2nd rotation in my list serves as a 4th cradle currently for budget reasons. I also own an Overgrown Tomb, should I use that for now as a placeholder for Bayou? Thanks in advance. Glad to FINALLY be a part of the Elves community. :)
