The level up keyword may not be around anymore, but the theme has continued with cards like Ascendant Spirit, Warden of the First Tree, Evolved Sleeper, and Surge Engine
Dovin, Grand Arbiter Dovin, Grand Arbiter pretty much just pumps out Thopter tokens, if youre looking for artifact synergies
This is a card good enough to see play in Pauper, Pioneer, and Legacy, so its safe to say itll play great in Draft or Sealed too
My mind immediately goes to cards like The Ozolith and Resourceful Defense to start shuffling around counters, not to mention synergy with cards like Elenda, the Dusk Rose and Unruly Mob that grow whenever your creatures die
This is effectively a blue Heroic Intervention for counter decks, with a bonus proliferate trigger to make sure you run it over Negate
the casting cost is to play the card from your hand normally, while the renew cost is specifically to exile the card from your graveyard for its renew effect
