What is the easiest standard deck to construct right now?

Apologies in advance if this gets asked a lot. I just want to play standard ;_;

What is the easiest deck to make without spending tons of money? I have like 6 Rare WCs, 6 mythic WC, and like 20 of each common and uncommon.

Both Azorius Convoke and the Oculus deck seem to not use that many rares?

As a sidenote how am I supposed to get Wild Cards without outright paying for them. Is it impossible?

Thanks.
