This is actually a 4-drop in Vintage. So its comparable is Jace, the Mind Sculptor. Very much harder to play turn 1, but easier to play turn 2, and both probably hit the sweet spot in turn 3. It's overall impact of the game seems... broadly similar? A personal Howling Mine that also had an inefficient but non-trivial impact on the board. A pseudo-planeswalker that trumps other actual planeswalkers in grind mirrors. Don't know how to really evaluate that cost reducer at this rate though.
It won't fit in Ravager aggro in the same way that you'd never even think of JTMS in Delver, if you care at all about your mana curve.
But if you ever cared to move away from the tempo aggro positioning when play Workshop, it's conceivable to see this as a grindy curve-topper to a grindy strategy that attempts to extract max rate per card (JTMS in every success Island-based grindy strategy in the decade setting a precedent)
This feels way more cohesive than Staff of Nin. The first three abilities line up way better. The fourth one is just weird though.
