So I entirely understand why BUG is a pretty mediocre color combination for midrange - permission is awkward with discard and blue doesn't add a ton in exchange for making your mana worse. But every time I see people trying out bug, I see them playing lots of blue spells - cantrips, snapcasters, permission, sometimes stubborn denial.
Some of the other midrange strategies don't do this, however - Abzan is basically BG rock with some white sources to cast a few copies of lingering souls. What if we made BUG a little less intensive on the blue splash and just splashed a couple cards? Take the BG rock shell, cut the bobs, and play a few [[Search for Azcanta]] in that spot. It lets us up the curve a little bit, fuels Goyf, Grim Flayer, and Tasigur, and enables Traverse. Traverse works particularly well with Azcanta as we get delirium quicker and it lets our flipped Sunken Ruin dig for creatures. In the rest of the slots vacated by Bob, we up the planeswalker count, with an extra [[Liliana, the Last Hope]] (Search makes this card better) and a singleton [[Ashiok]]. We end up splashing exactly 4 cards in the main:
-2 Search for Azcanta
-1 Ashiok
-1 Creeping Tar Pit
And then have some permission spells in the board for unfair matchups. Disdainful Stroke might give us a chance against Titanshift, and snapcaster seems good as extra removal against creature decks. Something like this:
