MTGGoldfish, MTG Melee, MTG Top 8, MTGAZone, AetherHub, etc. These won't all be Arena-focused, some specialize in tournament decks, others have user-submitted decks that may or may not be worth building, but the major thing to look out for is budget decks for tabletop won't necessarily be budget on Arena as in paper certain rares and mythics may be dirt cheap while on...

Arena has better third party tournaments when it comes to prizes. You can find these tournaments on mtgmelee.com.

Untapped is better for on-the-fly info, I use it to know what cards remain on my deck and what are the odds of drawing them.
