@stuart I have been playing with 2-3 MD online the last few weeks. I was lucky enough to play against @Oestrus in the Vintage Challenge this past weekend and did get to have the ultimate joy of naming Bazaar with Spyglass game 1 against Dredge. Then Erin proceeded to steam roll me games 2 and 3 with 4/4 and 5/5s. Oh the irony. I am supposed to be the one attacking with 4/4 and 5/5s.
It's hard to evaluate the card still. Besides the best play of naming Bazaar, the fact that it lets you see your opponents hand is critical early on. Waiting to cast uncounterable TKS is fun, but by then you may have already had your Temple wasted or you set COTV to the wrong number. I have named Tarn (hitting 2 tarns) to only have the opponent draw Volc. I have named Dack to have the opponent draw JTMS.
I am still on the 2 MD plan right now. For EW, it is a bit different because of budgetary concerns with players. Dredge will probably be more represented in paper than online. Remember priest and Cage do nothing against Hollow one and Gurmag Angler. Stopping Bazaar does stop both of these cards from landing, indirectly. Spyglass is the best at this.
Remains to be seen if this card is worth it.
