Mishra's Bauble is an old 'freetrip' artifact:

Artifact
Tap, Sacrifice Mishra's Bauble: Look at the top card of target player's library. Draw a card at the beginning of the next turn's upkeep.
People generally don't like the 'delayed cantrip' mechanic, but while discussing the new mulligan mechanics, it occurred to me that combining the bauble and fetchlands could give a "free" scry-like effect if you activate the bauble targeting yourself, and then activate a fetchland if you don't like the top card of your deck.

Naturally, the cantrip-delay means the bauble isn't great as a top-deck later in the game, but it's also not completely terrible since it does replace itself.

The bauble also has a bunch of smaller synergies as a token artifact, graveyard filler, or generic draw effect.

That makes me think it could work quite well to help stabilize the draws of a deck like burn which plays fetchlands, has limited card quality tools available, and doesn't try to combo by cycling through draw effects in a single turn.

Is this a technique that people have experimented with and discarded or is it a bad idea for some obvious reason that I've missed?
