I think all the various 3/1 creatures with upsides are better, and there's a few of those now. And I don't even have room for any of those variants. These might be fringe-playable at 720+, since I like that the 3/2 mode can be controlled by you, but I can't see them making the cut in cubes smaller than that.
Hey, someone's probably already told you this, but there's something weird going on with the card image for animate dead in your cubetutor list. It looks like a cropping issue. Not sure how hard it is to change as I don't use custom images for cubetutor, but since you went to the trouble to use custom images thought you'd want to know.
The image is correct. It's a miscut Animate Dead.
There are several in the cube if you want to browse through the visual spoiler.
I like to represent the frames if I can, but not for any of those. I'm going to wait and see if they do ones for other 'walkers. But there's a 0% chance that I run any of those over the better options we have now.
Oh, and both Miscalc and Forbid have gorgeous old-frame foils available with great artwork.
Running incomplete cycles is perfectly fine, so long as all the guilds have the same total number of fixing lands. In fact, running custom-built cycles is arguably better. Not every color-combination plays the same, and they don't all want the same kinds of fixing.
