Ever since using that Ode to Huy team (the one with Blissey) I've been in love with Rotom-Frost for reasons I can't really explain. I mean, it gets the same little tricks as washtom with its scarf set, but it trades cool resists and the ability to hit Heatran hard for 100% accurate blizzards. I decided I might want to build a different team with it, this time one with actual Aegislash checks instead of Specs Fire Blast Gyarados and Mud Bomb Blissey. I also thought I might carry some actual Kanga+Heatran checks (though this team still doesn't have many ways to beat it, I at least have a few much more solid ways of killing Kanga than Specs Gyarados). I also built this team around Christmas so thought Blizzspam would be fitting
Talonflame: This is what I mostly use to get rid of Diancie and stuff early game so that Blizz spam can clean up later. I also get to dent annoying things with BB and have Flare Blitz as one of my ways to beat Aegislash.
Abomasnow: Provides Hail for the 100% accurate Blizzards and helps get rid of things like Rotom-W for Talonflame and Rotom-Frost. It also gets its own priority in Ice Shard if I need to do something like quickly finish Lando-T or a Dragon.
Rotom-Frost: Running HP Steel to get that sneaky KO on Mega Diancie and enough speed to ninja Adamant Scarf Landorus-T with Blizzard, this thing is really fun to use. You can bounce away with Volt Switch near the beginning of the game, which I guess makes it a cool lead pick (it's also good because it completely counterleads people dumb enough to lead genies against hailspam :B). It's also got a key resist to Brave Bird that other Blizzard mons usually can't offer and outspeeds and OHKOs Talonflame with Volt Switch or even Thunderbolt (sometimes if the Talon has already taken a hit it can Blizzard KO too!) so I really like this mon.
OH and yeah it has a better MU against Charizard than other Blizzspammers.
Landorus-T: Explosion is literally the only reason to ever use this thing because suicide is always the answer.

The Intimidate patches up some weaknesses that the team has like Kangaskhan and Talonflame, and EQ can help vs Heatran.
Gardevoir: I ran this because it helped get rid of some of the Dragons. You may be wondering "how do dragons threaten a team with blizzspam lol???!?!??!" but there's literally 1 thing on this team that can switch into any move from Latios/Hydreigon and that's Aegislash, and even that takes SE Earth Powers/Fire Blasts/Dark Pulses from Hydra; everything else gets chunked by everything and Draco just OHKOs anything I throw at it aside from Aegislash so you know Gardevoir was an ok idea. I ran a bulkier one though because I thought Hail/Talonflame could finish off things like Latios or Kyurem-B that may live a Hyper Voice and by that time I really wouldn't care about Gard anyway, but the bulk is to maintain switching power. I fit it with Taunt and HP Ground in order to beat TR and hit Heatran better because Psyshock wasn't needed.
Aegislash: This assisted in solving the major Charizard problem that was prevelant all across the team (RIP resists) because it got Wide Guard I guess lol. This also stops Hyper Voice Sylveon and Rock Slide Landorus-T from completely fucking me over and forces a switch against Choiced variants. It can beat things like Mega Kangaskhan, Kyurem-B, Latios, Sylveon, and Mega Gardevoir, which are all pretty threatening as well. Finally, it's a ghost resist that I can freely go BOOM next to with Landorus-T :)
When I get back from lunch I'm gonna write something about how the team came to be.
So basically this team started with Rotom-Frost+Abomasnow because blizzspam christmas stuff (Abomasnow was originally Mega too)
I then added Hydreigon as a cool Heatran check because it resisted both of its main attacks and hit it hard with EP. It also helped out against TR by hitting Cress and Reuniclus hard with LO Dark Pulse.
I then saw that I had like 0 resists to Hyper Voice/Rock Slide and 1 resist+2 weaks to Heat Wave and decided Wide Guard would be good. I decided Heat Wave would be less of a problem than Hyper Voice/Rock Slide because Heat Wave would be mostly seen on Zard/Heatran and I could win easily against Heatran in theory because I had a mon that perfectly switched in and KOd and zard would have to deal with weather war bullshit (but that wouldn't be so hard for zard tbh). Rock Slide could've bit my ass if something that I couldn't hit well like Terrakion were to use it because I had 0 resists and 2 mons weak to it. Hyper Voice would be even less manageable because I had no way to hit things like Sylveon/Gardevoir yet. I added Aegislash because of this, and I guess that would work out well with Hydreigon because of their great synergy together.
At that point, I noticed the team would be a major improvement from the Ode to Huy team because my best way of beating Kangaskhan with that was by use of a Gyarados that got outsped and 2HKOd by its Return after Intimidate debuff, and this team has an excellent way to beat Kangaskhan in its mortal enemy Aegislash (it's not Gengar because Aegislash can lose vs Kanga too and Gengar can't).
Now I decided to bring my concern to Mega Diancie. It could OHKO everything but Aegislash and all I had to stop it was Flash Cannon/Wide Guard from Aegislash.
I also had a big concern about what I would do against anything that had Tailwind.
I came to the conclusion that the best thing to deal with this problem was Steel Wing Talonflame. This also was my best check to opposing Talonflame at the time so I ran Jolly to fulfill that role a little better.
Adding Talonflame to my team made me change the entire dynamic of how I pictured a game with this team. It meant I could pick one of Talonflame hyper offense or Blizzspam to start off with and just clean up with the other in the later stages of the game.
I had 0 switch-ins for Latios aside from Aegislash, and this is also where not worrying about Heatran earlier in the process almost became the death of me. I had 1 thing to touch Heatran at all and it loses to faster Dragons and Mega Kangaskhan (flashbacks to the other blizzspam team where it did nothing vs Kanga+Heatran...)
I ended up going with an all out offensive Gardevoir with HP Ground to help with this, because Sylveon really just wasn't enough to beat Heatran because they're all homosexual timid sets now so I couldn't outspeed and HP Ground because it could just set up Sub for free. This made Abomasnow non-mega sash.
I eventually came to realize that Mega Gardevoir's sky high Special Defense was far more important than getting the KO on Latios because I could just let the slot do nothing while Talonflame/Rotom-F/residual hail damage finished it off anyway, and taking Heat Wave from Charizard/Heatran was far more important than doing a little more damage to Kangaskhan. I put Taunt>Psyshock because I figured Taunting Amoonguss and either forcing a switch or having it be shit would be better than killing it anyway (also I had 4 mons that dented Amoonguss with anything they used lol), and it helps against TR and sub Aegislash.
I started testing with this, and it SUCKED. It did 0 to Jirachi+Diancie, had big Aegislash issues (especially sub), and still had some major Kangaskhan issues. Heatran and Charizard Y were still incredibly threatening and I fucking raged everytime I saw Jirachi+Diancie just because I hate those two mons together .-. This was what made me change Hydreigon to Landorus-T because it fucks up Diancie+Jirachi hard and does way more to Zard/Heatran than Hydreigon could ever imagine doing. Also, I couldn't stop Kangaskhan from murdering everything on my team without Intimidate (still doesn't mean I don't take heavy damage from it, though).
Some final thoughts about this team: Hail teams rarely fix everything they need to, and generally end up looking like dirt shit, which is why it's unpopular (blizzspam hail is especially unpopular because you have to run multiple ice types which burdens your team with a huge need to cover the many weaknesses of the ice type). However, I cannot express my personal liking for Blizzspam in any way with the vocabulary I have, and it doesn't really play all too bad.
This is also the theme song of this team
