MTG Salvation

I currently run the following:

-Gitrog Lands Matter
-Mizzix Spellslinger Storm
-Queen Marchesa PillowPolitics
-Rashmi, Eternities Crafter
-Daretti Artifacts

I'm looking at rebuilding my Rashmi deck to be something with more focus than "get lots of value and ramp hard". I usually try not to duplicate themes or copy the same color combinations too many times across my decks. I've been thinking of either an ETB deck or a Tap abilities deck in Bant, but I was hoping the forum would have some ideas for deck themes that don't conflict with any colors/themes I already run. I usually like themes that let me do lots of things on one turn, and that let me interact with the game frequently.

Thoughts?

You could run a tribal deck (pick your colors for this depending on the tribe you want to win) or a hate bears deck (with Gaddock Teeg or Captain Sisay at the helm).

The easiest way for me to make suggestions is to look at what I have built. Probably my most interactive decks are Sydri, Galvanic Genius and Ghave, Guru of Spores. Both are pretty strong, and both are very, very wide open to interpretation - you can build them however the hell you please. Of the two I'd recommend Sydri more. Ghave is strong, don't get me wrong - he just tends to go infinite at a moment's notice, whereas Sydri is just as interactive, and maybe slightly more fair.

Roon of the Hidden Realm is a super strong deck archetype in Bant that does have interaction with what opponents are doing with ETB creatures. It doesn't play that many cards a turn, its more like a control deck however. Let me know if you want my list to see what cards you'd potentially need?
