One of my favorite budget casual cards is Broken Bond. Most decks can always use more removal, and with the card draw of your commander it’ll almost always serve as land ramp as well.

That is indeed a nice budget suggestion Phule451, thanks! And thanks for the upvote :)

I'm going to suggest a few evasive creatures I use in decks that care about that feature, they're generally higher MV, which I gather is an asset to you! Hope they're not too high budget for your plan! Thieving Skydiver is an evasive creature that can steal a mana rock or Sword, it can even scale up from there. Another I truly love is Sower of Temptation, which steals a body until it dies. If the stolen creature dies you can maybe flicker it (you can also upgrade what it's stolen that way), but it's also a 2/2 flyer. Not necessarily good enough (but strong enough that I feel they're worth a look), Thalakos Deceiver can steal a creature if there is something worrisome (and it's just an evasive 1/1 if not), Thalakos Dreamsower can lock down a problem creature (less useful if people are big on Haste or Craterhoof, very good if they don't), and Thousand-Faced Shadow can copy a creature while offering an evasive attacker in a pinch.

I like Sporefrog a lot, I even run it alongside Dawnstrider in a Meren deck that tends to get targeted. You can easily afford to discard the card in Edric, and the ability can happen each turn.

Edric is a cool deck, interesting choice to build on a budget!

Great, great suggestions DreadKhan! Thank you - will definitely include the skydiver, Dreamsower and thousand faced dude! these will fit perfectly in the deck. and they are cheap as well!
