A lot of changes are coming to this cube. However, I thought we would start with the easiest. It is high time we upgraded the mana base in the cube. I am cutting the Tri-lands for the gates/thriving cycle.
These lands are more draft relevant, and still provide flexible fixing.
Next, Wizards has outmoded all gates and tap lands, it is time we followed suit. The Dominaria lands have land types which is sweet, and the taplands from Streets of New Capenna and Strixhaven have card draw/filtering upside.
I often get the question, about why not upgrade the lands to something nicer, like shocks or pain lands. The fact is, I don't want a fast environment. At most, I could see going to temples. I want something much more akin to retail limited. As there are only 4 unsets in the history of magic, we have to be very careful of power outliers. For me, that applies to the land base as well. Obviously, you can run whatever lands you like.
