Don't use Hyper Beam on Porygon-Z. It just set-up bait. You Hyper Beam, if you KO then switch in like an AgiLuke and sweep your team. Lol. Always use Tri-attack.
I am curious as to how to fairs against other leads since it appears to be an anti-lead. It's an intresting sight to see it as an anti-lead and I hope it works.
Azelf- Dark Pulse 2HKO, they set-up SR. I view that has a win.
Aerodactly - Ice Beam 2HKO, they set-up SR. Same situation.
Swampert: Tri-Attack does 46.4% - 54.9%. You need to bank on hax to win. If not 3HKO. They usually set-up SR. Lose in my view.
Machamp: Tri-Attack does 53.5% - 63%. 2HKO. They Dynamic Punch you and do 153.1% - 181.4%. Very lose.
Metagross: Very lose. T-bolt only hits 32.2% - 38%. 3HKO or 4HKO. The set-up SR and more than likely KO you.
Jirachi: Same boat, but with less damage. 26.6% - 31.3% to be exact. Your probably Scarfed and they SR and then Para you. Very lose.
Infernape: Fake-out + CC = KO. Lose
Ninjask: Name something that beats this thing. Lose.
Roserade: Lol sleep. You switch and free set-up for them. Yeah!
Hippowdon: Ice beam does 59% - 70%. If they Stockpile you then do 40% - 47.1%. Even chance to 2HKO. If not it's a 3HKO. Win. They can only SR or Roar you.
Tyranitar: Er... fail. You barely dent it. Big Lose.
Heatran: T-Bolt does 23.2% - 27.6%. Lose.
Smeargle: Hmmm. Sash means you always sleep so... you bring down to sash and then they set-up entry hazards while you wake up. Lose.
Uxie: This thing tanks you. DP does 27.1% - 32.2%. I use DS Uxie lead so you lose big time.
Starmie: DP does 52.1% - 62.1%. 2HKO. Your either Scarfed or they beat you to the KO. Lose.
Well, Porygon-Z does NOT make a good lead as it only beats 3 out of the top 15 leads. The idea seems really neat and unique but it won't fly. The only lead who manages to sweep from the start is Poliwrath.
Well if this team is dedicated stall, all types of entry hazards, you pretty much need a spin blocker. A rotom form always is the right choice for any team.
All types of entry hazards on Forre isn't smart. Change atleast 2 of them.
Don't use Salac Berry on Lucario prehaps? In this Meta-game getting one is rewarding. Don't be greedy when you'll likely be 2HKO'd.
Roar always goes last so using Salac isn't smart. Mist is pretty silly on any pokemon unless you really fear DDNite or DDGyara or something along the likes. Other than that replace it.
Focus Sash doesn't work outside of lead without Rapid Spin support.
Once again, WW / Roar always makes you go last so speed doesn't matter.
Charge beam on a Blissey... Use T-Wave or something.
Honestly, use the standard sets off of Smogon before throwing random sets together thinking they work. It really doesn't turn out the way you want it to.
This team does need a lot of work and I hope my suggestions will help somewhat.
