Unfortunately, it doesnt do enough to be particularly powerful
This artifact relies on Energy, allowing it to synergize well with many older cards from Kaladesh
My take on the format, particularly Sealed, is that black and red are quite deep and their powerful removal support controlling strategies better than they do disruptive aggro
Basically, the note I got from everyone was that the vanilla version was confusing for no reason, so I ended up cutting it from Shadowmoor
The icing on top is that she allows you to return an instant or sorcery from your graveyard to your hand if your opponent decides to remove her, so you're likely getting value here no matter what
Creatures you begin to control later in the turn won't get +3/+3, vigilance, or trample
