I think you would stick with Stage Dive which also draws a card. (And people aren't even using that anymore)

In what world would you ever run this over Provoke?

Probably in the OTK decks since it's cheap buff to charge minion that can be traded. Can potentially add more significant reach when combined with to the front/faceless shenanigans.

This provides way more value, and you can run both.

With Foe Reaper 4000 , Magnataur Alpha orInfectious Sporeling in Wild.

Well I guess they finally figured out how to make this effect on a spell good. Tradeable is pretty much always good. +2/+1 on a 1 cost spell is good period, giving a minion rush is great. I feel like broom is probably still more overall useful. But this having tradeable is cool.
