I have to say that if you go RG you already have the colors to retrieve the cards you need from graveyard, be it Loam, Stronghold, Crucible W6 any thinkable dredge/retrace removal ever and so on
The W6 ultimate requires more setup for retracing, though. This + Trade Routes allows repeatable recursion at a minimal opportunity cost. There's a good reason why cards like Snapcaster, Arcanist, Baby Jace, etc. exile the cards to prevent such cases.

We'll see how those kind of decks are going to turn out, but with stuff like on-demand Terminus, I have a very bad feeling about this.
