Edric can be rather competitive, and I would not really place him under a budget heading. His optimized list may run a lot of cheap 10 cent creatures, but it also runs a lot of extra turn effects which can get very pricey. Obviously, if you're not going for optimized combo, you can scale back on that, but you are then left with a rather fragile shell that is very reliant on your commander.
From a more Casual side, I would recommend either Meren or Selvala from your list. Both can really bring in a large amount of value, which will still give you benefits even if they get removed. Meren may bring in a bit more perceived threat initially, but also can give immediate value, and naturally scales well.
A $50 budget is quite low, as I've built under that restriction before, but it should be fairly achievable, especially in G/x decks. G/b may provide a bit more difficulty on the removal side of things, while G/w may have a bit trickier draw, but neither should be impossible to overcome.
