Ill just go ahead and say all Himeno arts from Jungle and Fossil and all Komiya and Kusube arts in general
Sephiroth gives you the latter two out of the command zone, being a Blood Artist that can also cash your creatures in for cards
If you've never seen Nadu in action, its ability (revealing the top card of your library whenever one of your creatures becomes a target of a spell or ability, then putting it into play untapped if it's a land or putting it into your hand if it's not, twice each turn for each creature) creates not infinite but sort of functionally infinite loops with an equipment that equips for free, like Skullclamp or Lightning Greaves
The original face choice is Sarah Jane Smith, but like the Fourth Doctor shes rather underwhelming, likely to produce a couple clues each turn but not much else
The back face is even worse, comboing with Niv-Mizzet for an instant way to win or draw out your deck for Laboratory Maniac
I'll note that in contrast to some of the darker planes, Moag was made to be brighter
