I've lost many a game already trying to wish for Ensnaring Bridge against an aggro deck. I think there is a reason most of the decks have Wurmcoil and/or Batterskulls instead, but its not like those aren't cards that decks already should have answers too as well.
This certainly has a niche. I'd consider it borderline playable in a Dredge deck as I'd put it as a cast-able DR target. Its also probably worth testing in Survival builds as mentioned about.
Sphinx of Lost Truths has both the body+bazaaring effect, is 2 mana more to draw 1 extra card + get 1 extra toughness (with a kicker of 2 more to not discard). This card certainly has the edge in efficiency.
The next closest is Magus of the Bazaar. That is cheaper and re-usable, but has no effect in combat as its a 0/1 and you need to untap to get its first usage. I think if you are looking for multiple Bazaar activations this card makes more sense.
As is the pitch ability is straight garbage though, it’s basically like bad pyrokinesis. So the power level gap between the Red Force + the Blue/Black/Green Forces is dramatic.
Red force more seems like a card you want to cast on your own turn, and even then it’s a bad version of ball lightning (of which there are a dozen versions).
I think Urza attacks from multiple angles is unaffected by Null Rod / Storm hate, and still provides value against removal. If it wasn't going to cost $9 million dollars, I'm sure it would find a home in some Outcome lists, at the very least as a singleton.
Even if its exile based mill, mill is almost completely worthless against Workshops and some other decks. You'd have to make the X number excessively high, like 15+, which would be a huge power creep from mill effects in the past and would adversely affect the format.
Heartstone the deck size is literally half and the biggest mill deck functions by putting more cards in its own deck (rather than reducing its opponent's deck size). I think its almost totally different here.
