http://replay.pokemonshowdown.com/ru-299178746 - had a pretty fun battle against
Double01 that I wanted to showcase as it kind of shows off some higher level predictions / switches and some underrated mons / sets.
Early-game: Neither one of us really commits to too much, but this also shows that you can be aggressive without risking a lot. Both of us do this a couple of times, but make sure that it's in a way that the other can't take advantage of it and win the game early. This is kind of common in higher level play when both opponents know that the other player is skilled enough to quickly capitalize even on slight mistakes. There is a highly unfortunate bit of hax that happens early as well, which ends up turning the tide of battle later.
Mid-game: As we progress to the middle stages of the game, I'm able to identify Flygon as my best chance to win this game. However, I do take note of the fact that d01 doesn't really actively send in Houndoom that much, which makes me believe it's a Choice Scarf variant. This means I know I have to save Flygon at all costs. Once I force Escavalier to take damage from Abomasnow, I know I can click Outrage and get some kills late-game. At the same time, I realize that Houndoom is his likely win condition, so I know I need to save Hariyama just in case I'm forced to Outrage early with Flygon and it backfires. In turn, d01 does a good job of saving his Sigilyph throughout the middle stages of the match, knowing that it will force my wincon to use a riskier STAB move to reliably clean and it also completely destroys my defensive answer to Houndoom that I'm saving up.
End game: Well, watch for yourself to see who won!
Underrated Sets: Assault Vest Hariyama (me) - AV Hariyama is a fantastic check to virtually all Fire-types in the tier aside from Delphox. With some Defense investment, it also becomes a very reliable answer to Mega Glalie and (Mega) Abomasnow as well. It's a virtual hard counter to any Houndoom set, as shown in this battle.
Physically Defensive Torterra (d01) - PhysDef Torterra may not be as good as the offensive tank variation, but it straight up hard counters Mega Steelix, Rhyperior (unless Ice Punch) and can at least check every physical attacker in the tier incapable of hitting it for super effective damage. It does struggle a lot with Fire-types and won't do nearly as much to targets neutral to its STABs, but its viability is shown here in taking literally nothing from the standard Mega Steelix Heavy Slam and it kept me from doing a whole lot with Scarf Flygon early and mid game.
SubNP Houndoom (d01) - Tbh, this is the first time I've seen this set used by anyone, and it's kind of scary late-game. Base 95 Speed is amazing with Salac Berry and if this gets off a Nasty Plot, you're done without a defensive response. I thankfully had Hariyama to hold it off long enough, but that doesn't make it any less scary if you lack a resistance to both STABs.
Regular Abomasnow (me) - Normal Abomasnow is really underrated. In this battle, it does a very good job of wearing down the primary resistance to Choice Scarf Flygon and it is able to to this for just about any late-game sweeper / cleaner that has issues getting through bulky Steel-types. The higher base Speed ensured that Abomasnow was able to get off the extra hit on Escavalier before going down, meaning even Outrage would have finished off Escavalier if it came to that.
