I believe the next two picks must be used on pokemon who can set up or clear hazards. To me, it doesn't matter what order it is done in, but making sure Dragonite has its Multiscale intact when switching in and Talonflame and Kyu-B get butt-fucked but Stealth
Cocks Rocks are what Team 2 really needs to focus on if they want to pull off the upset on Team 1 (they're the underdogs simply because of Team 1's last pick advantage). Right now, three pokemon that I have been looking at are Bisharp, Tyranitar, and Garchomp. There has been some talk regarding Excadrill being the spinner for Team 2, but the mention of a scarfed Exca makes me want to grind my teeth. That's why a Sand Rush Excadrill+T-tar combo would be pretty nice to have. However, that encourages an Azumarrill pick since it shits on 5 of Team 2's 6 potential mons. This also hinders the idea of a Garchomp pick since it cannot switch in on Azumarrill either. Not only that, but it can't really do shit against Deoxys-D either. Bisharp is able to handle Talonflame pretty well and doesn't get completely mauled by Azumarrill unless it carries Superpower, but then it becomes set up fodder for Mega Scizor. Not only that, but it has the utility of Knock Off, priority in Sucker Punch, and Defiant to discourage the use of Defog.

Bisharp is the beast that will be able to break through the sturdiest pokemon on Team 1 by using its STAB attacks. Along with that power, The utility it brings in just 4 moves is overwhelming as I have already noted above. It obviously fears Landorus, but so will most pokemon that will be chosen, and Kyu-B can hit it hard with EP. It doesn't really give any type of fucks about Deo-D or Ferrothorn even though getting its LO knocked off can hinder its attack slightly and being paralyzed isn't too big of a deal outside of parahax. Talonflame can't really hit it hard, but Bisharp would have to be burned by WoW. That is why I was trying to look for a special attacking Dark or Ghost type that can lay down SR but the latter is impossible, while the former...actually doesn't exist either lol. The reason for the EV's being weird is so that Sharp can outspeed Deo-D and to maximize its bulk while preserving its max attack. I was really contemplating putting a Lum Berry on Bisharp, but due to the fact that would diminish his power to break through Deo-D, I had to opt for Life Orb. Of course, a Defiant boost completely nullifies this and a Lum Berry would be incredibly useful against Ferrothorn and, more importantly, Talonflame. Here are some calcs in regard to Life Orb vs no Life Orb:
252+ Atk Life Orb Bisharp Iron Head vs. 252 HP / 0 Def Kyurem-B: 367-432 (80.8 - 95.1%) -- guaranteed OHKO after Stealth Rock
252+ Atk Life Orb Bisharp Knock Off (97.5 BP) vs. 252 HP / 252+ Def Deoxys-D: 226-268 (74.3 - 88.1%) -- 6.3% chance to OHKO after Stealth Rock
252+ Atk Life Orb Bisharp Knock Off vs. 252 HP / 252+ Def Deoxys-D: 151-182 (49.6 - 59.8%) -- guaranteed 2HKO after Stealth Rock
252+ Atk Life Orb Bisharp Knock Off vs. 248 HP / 8 Def Talonflame: 195-230 (54.3 - 64%) -- guaranteed OHKO after Stealth Rock
252+ Atk Life Orb Bisharp Knock Off (97.5 BP) vs. 4 HP / 0 Def Landorus: 242-285 (75.6 - 89%) -- 12.5% chance to OHKO after Stealth Rock
As you can see, LO+SR is crucial in Bisharp's ability to destroy everything in it's path. Ferrothorn isn't very breakable and Sharp takes too much damage from LO+Iron Barbs to attempt to attack it for the most part.
252+ Atk Bisharp Knock Off (97.5 BP) vs. 4 HP / 0 Def Landorus: 186-219 (58.1 - 68.4%) -- guaranteed 2HKO after Stealth Rock
252+ Atk Bisharp Sucker Punch vs. 4 HP / 0 Def Landorus: 153-181 (47.8 - 56.5%) -- guaranteed 2HKO after Stealth Rock
Without LO, Bisharp can still 2HKO Lando switching in with Knock Off+Sucker Punch thankfully, but loses its ability to have a chance of OHKO'ing it. However...
252+ Atk Bisharp Iron Head vs. 252 HP / 0 Def Kyurem-B: 282-332 (62.1 - 73.1%) -- guaranteed 2HKO after Stealth Rock and Leftovers recovery
252+ Atk Bisharp Knock Off (97.5 BP) vs. 252 HP / 252+ Def Deoxys-D: 174-206 (57.2 - 67.7%) -- guaranteed 2HKO after Stealth Rock
252+ Atk Bisharp Knock Off vs. 252 HP / 252+ Def Deoxys-D: 116-140 (38.1 - 46%) -- 23.8% chance to 2HKO after Stealth Rock
252+ Atk Bisharp Knock Off (97.5 BP) vs. 252 HP / 8 Def Talonflame: 222-262 (61.6 - 72.7%) -- guaranteed OHKO after Stealth Rock
Bisharp won't be able to win 1 on 1 thanks to not having LO against Kyu-B and Deoxys-D. It will be able to stay in on Talonflame since it can use a Lum Berry to soak up the burn, but I don't think the Talonflame user would opt for that since it would just lead to a dead Talonflame. T-flame would be able to Roost to get its health back but Bisharp would still win in the end in a very stall-y battle since Roost has less PP than KO. Like I said, with a Defiant boost, LO is completely unnecessary, but it cannot be guaranteed to occur. After all this, I am starting to like Lum Berry more but I still think Life Orb will be more useful due to the power boost it gives. If anyone would like to give their thoughts on it than by all means go for it.
EDIT:
Just rememberd that ttar would ruin dnite multiscale, still Bisharp is capable of setting rocks and resist BB...although its stats are considerably lower.
Sand would not exactly ruin Dragonite's MS because sand damage happens before Lefties recovery.
