i would recomend that you get air superiority and flight as a movment set. As nearly every single tank you come across has gone super jump or super speed. And the few that have flight you can knock out the air with either web grenade or if they get to close air superiority.
Also i got grant invisibility + invisibility it gives you stealth pets which you can then pick and choose your fight. Some tanks can see through your invisibility which is a shame but when you go up against squishies it doesnt stop them.
I would Also say plan your build so you have at least Caltrops/Acid motar/and posion trap all three of these are very very handy at preventing other stealthers from sneaking up on you as well as reducing the resitances of other fighters.
Other than that i would say just be prepared to be attacked by spine scrappers alot.
Get fly as travel power and be prepared to fight lots of spineys?? Something's weird here :-s
Fly and acid mortar work well together, yes-no?
Ahem.
Id rather advise to take teleport pool as a travel power, utilize group teleport for moving with your bots and FF generator/seeker drones, and you also get teleport foe to tp squishies into your poison trap+caltrops+mines.
I dont know enough of traps to give advice, but most stuff in there looks useful. From robots take naturally summons and upgrade/equip. Instead of repair, Id take aid other and aid self.
Well, these are just my ideas.
Ok guys 
thanks
Mastermind PvP is based on a single context - get your enemy to stay put while your henchmen batter them accordingly.
Traps is single-handedly one of the best sets for doing this, given enough time to prepare.
Caltrops and Web-grenade ensure a slow, non-jumping, non-flying opponent. Poison Gas Bomb (forget the name) gives a chance for toggle dropping with its sleep/hold components. FFG and Triage Beacon gives you some protection against hostiles. Seeker Drones gives you additional control with -Percep and Disorient. Acid Mortar to whittle away your opponents resistance.
Robotics gives you Burn Patches, Disorient Grenades, Force Shields, and Repairs for your Robots. Along with Energy/Knockback Damage.
I'd try and tie in Teleport Foe, and Teleport for travel - enable yourself to flee in good order, and to pull enemies back into your deathtrap.
Myself as Robotics/Forcefield I tend to be a moving battleground as my defenses (Force Bubble, Dispersion Bubble) aren't so static. Traps need to pick their own battleground more.
i would recomend a stealth power as well so you can pick your targets also its funny standing around visible while all your bots are invisible
Oh and somebody told me that triage beacon doesnt work on henchmen, is this true?
Imo all Mastermind should get into the 'moving fortress' mindset. If you are separated from your henchmen and bodyguard drops, a blaster can 2 shot you.
