You are trading off opening hand explosiveness for a card that's pretty mediocre in mirrors where Shop players are copying each others 75s of ABR, WB, WL. Tangle Wire can impact the board and let you push through lethal in otherwise unwinnable board states, wire can allow you to draw into business where you'd otherwise be dead because you have no blue cards.
It could be the kind of card that moves in and out on the play and draw. We tested some BUG lists vs. internet shops and I can tell you I had to force the card a few times on the draw. Hands like Verdant, DRS, Wasteland, Force, Leovold, Blue Card, Removal ... you don't have to force a Sphere (it's defensible) but I feel like you have to Force Spyglass.
