Seems to me like there IS only one viable team to use with Durant. Looks like Truant teams are going to be much more monotonous than trick teams.
I've been running pretty much the exact same team as you for my battle subway run (Lost at 892), at 700something on my second try right now.
Your set on Whimiscott is probably going to fail you at some point.
1. You can't deal with Volt Switch and U-turn because you don't have Encore and took protect instead. The AI can easily U-turn away from Durant after fainting Whimiscott and serious screw you over with the next pokemon.
2. I think Sunny Day is not worth it over Memento on Whimiscott because any one of the many Flame Charge user will greatly mess up your team. You can't switch out Whimiscott, but you can't leave it in either. If you switch out to Durant, it will get KOed by flame charge. If you switch out to dragonite, you risk a burn, which will be almost a 100% guaranteed loss. If you don't switch out, then you have a +2 speed flame charge user that's faster than Durant and threatens to burn/annoy Dragonite.
3. Don't remove Substitute. It's the only thing that will keep you alive against stuff with Sash/Sturdy Counter/Metal Burst, which is not uncommon. It also means QC things don't instantly kill your dragonite. Since you can already stall out the PP of steel types with Durant and Dragonite, you don't have THAT much trouble with them.
4. I'm not sure why you're running 252spe on dragonite. If your Entrainment works out fine, then you're far faster than anything in the BS, even without any speed evs. I think shifting the speed evs to attack would be better so you can OHKO stuff without risking that they break your sub and leave you vulnerable to the next pokemon.
Can we post streaks that are still going? I have a 105 Truant team and I haven't lost yet.
Whimsicott @ Focus Sash
Timid
flawless IVs
252 Speed
Taunt
Knock Off
Protect
Sunny Day
My lead. Nearly guaranteed to get a Taunt off and still be Taunted when Durant comes in. Protect because if I live after using Taunt and Knock Off, Taunt will wear off and Durant can be Protect stalled.
Durant @ Choice Scarf
Jolly
flawless IVs
252 HP/4 SpD/252 Speed
Entrainment
Superpower
Protect
X-Scissor
Durant is a deceptively powerful pokemon in the Subway, nuff said. Entrainment Truant is just OP when the AI rarely switches.
Dragonite @ Leftovers
Adamant
flawless IVs
Multiscale
252 HP/4 Atk/252 Speed
Dragon Dance
Protect
Substitute
Dragon Claw
The star of the team. I switch in, Protect (except if Durant gets killed after Entrainmenting), Sub, Protect, then DD + Protect stall until I'm ready to sweep with Dragon Claw. Sub lets me avoid priority and OHKO moves.
Should I remove Sub for Fire Punch? Nearly every problem I've had was against Steels. Only leaves a very painful weakness against Sash Horn Drill Rapidash, since Sash Garchomp can't OHKO with Outrage unless I'm not at full HP for some reason.
