Since I first tried this out, I’ve continued to use and refine it. At this point, I’ve play tested it in all of the nastiest zones. Bloodshot Ramparts, Southpaw, the Beatdown, Lair of Infinite Agony, the Rustyards, WEP, and more. I’ve run the circles of slaughter, and breezed through my first try at an OP8 Peak run with it.
This is the current version of the skill distribution:

When it comes to gear, there are a few specifics that really make it go:
(Blue rarity) Blurred Trickster, +6 CR, ideally with +5 KR as the secondary
Big Boom Blaster + singularity grenades. I go with a Quasar or slag singularity.
Bone of the Ancients-- collect 'em all. Default is corrosive, if you don’t want to bother matching elements, or are using Jakobs weapons.
For guns, anything that plays well with CR works great, but Pimpernels and the Bekah are flat out superior choices. Tattlers, Slagga, Maggie, Practicable Face Time, Conference Call, Anarchist, Stinger… All fine choices.
As for play quirks, this one is much like other Trickster builds, except that it more often favors shooting right at the bubbled target to set off chains of SS and throw extra Ruin and Converge around. Since you have KR on board, it is pretty strong against many ranged attackers. It also turns into a booster-sprinkler when you catch a DoT. As a general rule, I’ve been keying in on controlling rushers-- Rabids, Ironclad Lunatics, suicide bombers, and so forth.
Singularities serve a few purposes here. Throwing one out to start puts enemies closer together, so Sub-Sequence hops are shorter. It also means that each instance of Converge pulls enemies closer for Helios and Cloudkill blanketing, which is actually effective damage. Third, and importantly, singularity stuns help buy time during cooldown.
