This will be an unpopular opinion: the main reason why I picked Slaking is because of its 670 BST that always allows me to be the top trainer on the board, ensuring the godsend win in tie matches.
This Pokémon is a beast for real, don't get me wrong, but I think that until streaks will just rely on it, hax will always win in a brutal format like Singles 2v2.
Without hax, of course, Slaking can win alone vs. almost every Pokémon, and with opponents' reduced EVs it doesn't just gain extra power on the offensive side, but it can also afford to run a
Jolly Nature with
196+ Spe EVs to reach the needed 159 speedtier (the old 173 one), basically outspeeding 120 BST Spe and everything slower, something that in other Facilities it cannot do. Then it must have of course max Attack investment (
252 Atk EVs), while
60 SpD EVs are really blessed vs. Dome's weaker Special attacks and its HP Stat is naturally so high that it would be sub-optimized to further invest there.
Choice Band is absolutely mandatory and the moveset is pretty straightforward:
Double-Edge is the main attacking move, with an insane 180 Power (factoring STAB) that can achieve an amazing list of OHKOs vs. 3 HP / 3 Def IVs Dome's foes even with a Neutral Atk Nature.
Shadow Ball and
Earthquake are the preferred moves for coverage, since Brick Break is really needed just vs. Tyranitar in Open Level in my opinion.
In the last slot I've opted for
Hyper Beam because it's the only move that can ensure an OHKO on notorious Lapras 7/8, while sadly Double-Edge needs a roll to OHKO.
Gengar is the most versatile Pokémon in this facility, and I can't really imagine why a team should not bring it in the selected trio.
I've recently abandoned my dear Perish Song Gar in favour of a more offensive set, that has the same moveset of
Ezio 's one.
I made this change after discovering opponents' reduced IVs, that boosts a lot Gengar's offensive presence and basically it's the only reason that can justify an offensive set, totally sub-par in other facilities.
Thunderbolt and
Ice Punch create the notorious BoltBeam combo, while
Destiny Bond is the best move available in Dome considering tie mechanic that will always make you win if you are on the top of the leaderboard.
I've selected
Substitute as the last move since it is really helpful vs. Status users, giving me momentum even on switch-ins thanks to my
Lum Berry, and I can also spam Subs to lower my health and ensure the double kill with Destiny Bond.
I run
Modest Nature with
228 Spe EVs since a +Spe one is not required for Gengar to reach the "new" blessed speedtier, that due to 3 IVs foe is now set at 159 (173 before). I then used
252+ SpA EVs since it allows me to achieve the most on the offensive side (especially the ensured 2HKO on Armaldo and the greatest chance available to score a 2HKO on Lapras 7/8).
Then I've put
12 HP EVs to create 4 perfect Substitutes remaining at 1 HP,
12 SpD EVs to make a defensive jump on Special side and
4 Def EVs not to waste them.
Here we are with the true star of the team.
At the beginning I thought this would've been a filler spot, a Pokémon just brought vs. Tucker and maybe vs. some Rock trainers.
I was totally wrong: this Suicune is a true monster. Thanks to
Timid Nature and
244+ Spe EVs she can outspeed 110 BST Spe and everything slower. If you have followed my recent Moltres adventures, you already know that if a
Leftovers Pressure staller - with
Protect and
Substitute - outspeeds a foe, it can drain 32 PPs from that enemy just switching between these 2 moves, even admitting that a foe has 32 PPs from moves able to break Subs (and there's no Pokémon that can achieve such feat vs. Cune). Then I've put
140 HP EVs to reach the highest Leftovers number available, 193, and the rest in Def (
124 Def EVs).
This set can capitalize on free turns behind a Substitute - or on Struggling foe - in a way that Moltres can just dream: thanks to
Calm Mind I can set-up at +6 SpA / +6 SpD behind a Sub, with
Surf of course as the only attacking move. Even if an enemy has Water Absorb, it's not an issue since I've just to stall it and then switch into my 2nd Pokémon vs. a Struggling foe to ensure the win - and Gengar can also set a Substitute on an out-of-PPs Water Absorb Pokémon-.
Suicune has lately become my first lead pick in more than 70% of matches (!), and more than 65% of them are won by her alone (!!!). She can set-up without any kind of support on every Dome slower foe without Quick Claw, it's nothing but amazing and I'm truly convinced she is the key of my team success.
There are no words to explain the buff that she has received with IVs glitch, but I want to report a consideration; in Dome Suicune can achieve calcs that would require these Base Stats vs. 31 IVs foes:
100 HP / 91 Atk / 129 Def / 118 SpA / 129 SpD / 98 Spe
Of course, every 31 IVs Pokémon you'll bring to the Dome will get this kind of buffs, but just imagine how OP and broken these stats are on a Sub/Tect Pressure staller with Calm Mind and a strong defensive Type like Water is.
The gameplan is simple: if you don't see a Lax or a faster foe in team preview,
BRING CUNE!
