Hi Penguin nice team you got there! However there are a few weaknesses that seem like real problems... For starters you don't have any phazing move, which is never good for a stall team. Yeah you have your failsafe, Jirachi, to fall back on, but this won't always be enough. For example how do you deal with SubCM Latias? It gets a free sub against Tangrowth, Hippowdon, and Zapdos, and even against Forretress which can be pp stalled out of Gyro Balls. Then it will deal one or two hits to your Scarf Jirachi as you break its Sub. Rinse and repeat, and eventually a good player using SubCM Latias will manage to sweep through your team, as Latias easily sets up against half of your team.

Same goes for SubCM Jirachi, to a much smaller deegree though as you have SpD Hippo, one of the best counters to it around. However Hippo without Whirlwind needs 2 hits in order to kill Jirachi and this is the problem. +1 Water Pulse 4HKOes Hippowdon, and with a little help of confuse hax you may not be able to 2HKO in time (all that Jirachi needs is you to get hit by confusion 1 time really, which has a 20% chance).

So as you can guess by now i am suggesting of putting a phazing move on at least one of Hippo/Zapdos. I would put it at both if i were you as i know how important phazing moves are for stall teams, but one is enough to solve the problems that i mentioned and i get that Rock Slide is needed on Hippo as Rona is a big problem so you should put Roar instead of Toxic on Zapdos.

Finally the other big problem of your team is that you use Forretress as your spinner without any form of ghost-elimination support, and i can't help but wonder how will Forretress manage to spin against Jellicent and Sableye teams. You may want to try Scarf Tyranitar for this reason, which can at least trap and kill Jellicent after Forretress uses Volt Switch and SR is on the field, while still acting as a failsafe for your team and being able to switch into Lati@s and even trap them and prevent them from annoying your team anymore.

tl;dr

Roar > Toxic on Zapdos or/and Whirlwind > Rock Slide on Hippowdon
Scarf Tyranitar > Scarf Jirachi

Good luck!

EDIT: Oh and something else i forgot... Since you are aiming to spinblock against Starmie, meaning that you use a SpD spread, definitely use Shadow Ball over Scald in order to 2HKO before Starmie has a chance to crit and 2HKO you with an Electric move (yeah defensive Starmie actually use Thunder, at least mine does).
