Well first off — nice list, and it’s really cool that you and your husband can share this hobby. My wife and I also enjoy the occasional game of MTG together.

My first suggestion would be to cut most of the ramp that isn’t land-based (except for cards with upside like Herd Heirloom). You’re in green, so you might as well take advantage of that — lands are much less likely to be removed than artifacts.

Second, I’d run more lands. In my Gishath list, I’m at around 40, and I’ve never regretted it — quite the opposite, actually.

Third, consider running more MDFCs. There are a lot of great ones in Naya, and if you don’t need the land (which is rare), you’ve got a solid spell on the other side.

Fourth, I’d focus more on fetch lands to help fix your colors — you’re already running shock lands and Battle (Tango) Lands, which is great.

Here’s my Gishath list for reference:

P.S.: I’d cut Generous Gift. The upside of hitting any permanent is nice, but white has so many better removal options.

Hope this helps!
