I can post a list if you want, but it basically breaks down into five categories. Keep in mind that everything I say here is in the context of my specific group and my tendency to want to build my decks heavily around my commanders, as opposed to running goodstuff with a utility commander.
-Land. Duh.
-Huge creatures. 28 of them in my case. If you can need a utility effect and it's available on a big creature, go with the creature version even if it's a lot less efficient. That means as much creature-based mana fixing (
Krosan Tusker,
Eternal Dragon), removal, and disruption as you can manage. Play as many as you possibly can, because investing six mana into a Mayael activation and getting nothing can be back-breaking.
-Utility cards. The kinds of things you would run in any deck. Removal, mana fixing, tutors. Don't run card draw, because you ideally won't be playing many cards out of your hand once you get rolling, and drawing a big creature is often a dead draw.
-Ways to protect Mayael. Equipment, auras,
Ghostway. She dies extremely easily and every time you have to recast her you're de facto increasing the cost of every additional card she gives you.
-Cards with specific Mayael synergy (
Awakening,
Noxious Revival,
Illusionist's Bracers) that don't fit into any other category. If you're willing to make the investment (and so far I haven't been)
Sylvan Library is incredible with her because it means you'll never accidentally get a creature stuck in your hand again and can filter for removal and land while ensuring your Mayael activates almost always hit.
Mayael honestly is not good. She's too fragile and her effect is fairly weak outside of synergies that let her use it repeatedly. You're paying nine mana to get your first creature, and you usually don't get to pick it, and it might not even work. But if you can get her set up without getting blown away every time she enters play you get creatures that don't cost cards and at instant speed, plus occasional craziness like tutoring for a silver bullet and then dropping it straight into play. She's fairly bad, but I love her. Getting those synergies running is fun, and I like never knowing exactly what you're going to get.
As for pictures, I'm always worried about showing off my Touhou Magic stuff in public because it's edited together out of art that I don't own and don't have explicit permission to use. I don't know precisely where copyright and manners fall on that kind of thing, but it feels sketchy.
What I can show off are the sleeves I use on the deck in question. I bought these (as well as a set of Sanae sleeves and a set of Tenshi sleeves) at a reputable online game store last year. Sometimes you can still buy sleeves from this line around, but they tend to go for much more than I paid for them now. Sorry for the poor image quality, I took this with my phone.
