Thornbite Staff and Basilisk Collar on Meren is the idea. An admittedly cute idea, which could very well be switched out for other stuff. Wilds Whisperer lady could end up tapping for the staff's cost.
As for the manabase, it's what I have. Dropping $50+ on a fetchland or $150+ on a dual land in a single go has to wait. I have a somewhat decent amount of basic land fetching (with a decent amount of basic lands to fetch), so I'll have to see where destiny / deckbuilding takes me. I'm not sure where else I would go with just a dual-color manabase though. Some kind of engine like Journeyer's Kite, or whatever non-basic it is that lets you play a basic from your hand?
I like having the journey of improving a deck, instead of just starting with some netdecked thing from somewhere.
