The bonus with displacer can be critical for your opponents removal, because the 3/3 body should be the common target, which leaves the little 1/1, but casting displacer later means trouble :wink:
Revoker simply is only a 2/1 which is blocked by some of his targets (DS, Mother etc.) too and is only good at an empty board (ANT; Belcher; Sneak Show etc.), which means i like him vs combo but we have enough other good cards against combo so i cutted him in favour of Ballista&Co.
@Eldrazi yes i have found any real Splash better than the simple colorless Versions but i still tinker with different ideas of the tentacle stuff.
Yeah - clearly a good improvment for this deck, even if you cant abuse it with displacer, but it adds up quickly if you have 4 Ballista, 4 Displacer and 2 Jailer at main - this alone can be a good start against various creatures, add sideboard removal spells and you get a good amount of removal stuff.

I lately tinkered around with various splashes/ideas.
For me the Blade Splicer/Angel Version is very solid and aggressiv - works good so far.
I also brewed up with little U Splash for Trinket Mage (tutors Ballista, Chalice, Mox/Petal,  B.Collar or T.Crypt from Side etc.) or little Bomberman-Style with 2 Auriok Salvager (to get back Ballista) and Lotus Petal over Mox. Alot of room for some ideas IF you dont fear Moon effects.
