Time Spiral removes itself from the game, which does not allow you to infinitely recur drawing seven cards, as you would with Timetwister (see further down the list)
It should see lots and lots of play in Standard, Pioneer, and Historic throughout its existence, earning it the top spot on the list
Stingcaster Mage Early shoutout to Reality Fracture newcomer Stingcaster Mage, which isnt out at the time of this most recent update
Bloodline Necromancer is also great in Inalla, Archmage Ritualist decks if you pair it with Ashnod's Altar or Phyrexian Altar
Then, of course, it wouldn't be a proper artifact deck without Master of Etherium, who's power and toughness are each equal to the number of artifacts you control, and other artifact creatures you control get +1/+1
