These lands are a great continuation of a great precedent (putting basic types on dual lands) but is not playable in Vintage. Or Legacy. Or Modern, probably. It's a good idea, and I hope they do more of it, but these particular cards are NOT the situational better dual that the Reserve List is looking for.
Again, however, I'm totally stoked these were printed and I think this absolutely the way of the future. Dual lands with basic land types are great for casual brewing, cube, and EDH, as they interact so well with older fetch cards. Cycling is a fine ability and these are fine cards. They're just not competitive in eternal, I don't think.
Thanks MaximumCDawg, now I don't have to write my own post in this thread!
Yep. All they really need to do is make the "comes into play untapped unless you control 3 or more lands" with the basic land types and we are pretty much there for new budget duals in eternal.
