Ardent Electromancer's floor as a Pseudo 2-drop might give him a role in aggressive strategies, if you have a Rogue and a Warrior on the battlefield already he can do a good Burning-Tree Emissary impression.
Triggers for every attacking non-Human, and the creatures go directly on to the battlefield and are NOT sacrificed at end of turn or go back to the hand.
I think this is pretty nuts and worthy of a Mythic.
Not only they are not sacrificed, they can't even be killed in combat. All the Splicers from New Phyrexia work great here.
I don't get why these soldiers can't at least have vigilance. I know it's been established that knight tokens get vigilance, but that seems to be a keyword that matters in this set, and it would make this cat slightly better.
Humans get fewer keywords in Ikoria, so the human tokens are vanilla but also more common.
So if I understand The Ozolith right, if I got a planeswalker that is currently a creature and it dies, the loyalty counters get moved onto it. And if I were to have say, a march of the machines plus mycosynth lattice, my planeswalkers would enter the battlefield as artifact creatures. So Ozolith would give the new planeswalker those loyalty counters.
You can do it in Standard with Sarkhan the Masterless and a sac outlet. This works really, really well with Modular, as you can both put the counters from the ability AND throw them on Ozolith (thanks to last-known-information for the triggers)
Her power level is very similar to Nissa, Who Shakes The World but being a card advantage engine instead of a mana engine. Very flexible in general, and very good with X creatures.
It's all in the layers, they don't lose their creature characteristics. Now you can have a Magus of the Moon with Humility for even more confusion.
