Tyranitar @ Focus Band
Ability: Sand Stream
EVs: 252 HP / 252 Atk / 4 SpD
Adamant Nature
- Aqua Tail
- Crunch
- Payback
- Snore
Dragapult:
252+ Atk Tyranitar Crunch vs. 0 HP / 88 Def Dragapult: 336-396 (105.9 - 124.9%) -- guaranteed OHKO
If the Dragapult uses Disable, just switch over to the other dark type move. Both Kill.
Mew:
252+ Atk Tyranitar Payback (100 BP) vs. 168 HP / 88 Def Mew: 338-398 (88.2 - 103.9%) -- 25% chance to OHKO after sandstorm damage
It says 25% chance to OHKO after sandstorm damage, but since mew can't recover, the next struggle is guaranteed to kill.
Rhyperior:
252+ Atk Tyranitar Aqua Tail vs. 248 HP / 116+ Def Solid Rock Rhyperior: 219-261 (50.5 - 60.2%) -- guaranteed 2HKO
A Metal Burst from Rhyperior does up to 392 damage, but Tyranitar has 404 HP and is guaranteed to kill the next turn. Rhyperior cannot OHKO with EQ.
Find me if you need proof
ok never mind apparently I already tested all three of above scenarios in the same game:
https://replay.pokemonshowdown.com/gen8customgame-1043228392
Edit: I just realized that the default format for Teambuilder is Gen 7 and that Tyranitar cannot obtain Aqua Tail legally in Gen 8.
Thus, here is a version that IS allowed in Gen 8:
Tyranitar
Ability: Sand Stream
EVs: 112 HP / 140 Atk / 252 Def / 4 SpD
Adamant Nature
- Iron Defense
- Rest
- Crunch
- Payback
Dragapult: Literally do the same thing as above (I'm too lazy)
Mew:
- If Mew imprisons turn 1:
--- 140+ Atk Tyranitar Payback (100 BP) vs. 168 HP / 88 Def Mew: 312-368 (81.4 - 96%) -- guaranteed 2HKO after sandstorm damage
--- 140+ Atk Tyranitar Struggle vs. 168 HP / 88 Def Mew: 52-62 (13.5 - 16.1%) -- possible 5HKO after sandstorm damage
--- Sandstorm damage: 6.25%
--- Adding up all of the above, the minimum damage is (81+13+6 [numbers are rounded down because I can't do addition with decimals]) about 100%
- If Mew transforms turn 1:
--- Iron Defense + Rest means that Mew cannot hurt the Tyranitar
--- Keep using Iron Defense to prevent the Mew from Resting
--- Since Transform only gives 5 PP per move, Tyranitar is guaranteed to stall out mew, as even a max attack adamant Tyranitar only does (252+ Atk Tyranitar Payback (100 BP) vs. 112 HP / 252 Def Tyranitar: 68-81 (18.4 - 21.9%) -- possible 5HKO) to this Tyranitar at +0 Def
Rhyperior:
Here is where things get a little concerning, and I don't know if it works 100%
- Tyranitar should Iron Defense up and use Rest whenever his HP is threatened
--- 0 Atk Rhyperior Earthquake vs. 112 HP / 252 Def Tyranitar: 216-254 (58.5 - 68.8%) -- guaranteed 2HKO
--- 0 Atk Rhyperior Earthquake vs. +2 112 HP / 252 Def Tyranitar: 108-128 (29.2 - 34.6%) -- 6% chance to 3HKO
--- 0 Atk Rhyperior Earthquake vs. +4 112 HP / 252 Def Tyranitar: 72-86 (19.5 - 23.3%) -- possible 5HKO
--- 0 Atk Rhyperior Earthquake vs. +6 112 HP / 252 Def Tyranitar: 54-66 (14.6 - 17.8%) -- possible 6HKO
- Tyranitar is basically guaranteed to survive the first few Earthquake hits, and is able to boost up to +6 Defense
- When Tyranitar is at +6 Defense, slowly whittle down the Rhyperior with Crunch or Payback. If the Rhyperior uses metal burst, use Rest immediately and do it again once woken up. Rhyperior cannot kill with 3 Earthquakes and a Metal Burst
--- 3 * 14.6[Earthquake] = 43.8%
--- (108[Highest Crunch Damage from Ttar] * 1.5[Metal Burst] )/ 369[Ttar max HP] = 43.9%
HOWEVER
- Critical hits exist, and will kill Tyranitar in all cases but 1:
--- 0 Atk Rhyperior Earthquake vs. 112 HP / 252 Def Tyranitar on a critical hit: 320-380 (86.7 - 102.9%) -- 18.8% chance to OHKO
--- 0 Atk Rhyperior Earthquake vs. +6 112 HP / 252 Def Tyranitar: 54-66 (14.6 - 17.8%) -- possible 6HKO
--- Added together, the above exceeds 100% of Tyranitar's Max HP
- Exception: Rhyperior crits Turn 1, in which case Tyranitar can just use rest immediately. If lucky, Tyranitar will wake up after one turn of sleep to Iron Defense, in which case Tyranitar will win given no further crits.
HOWEVER#2
- If the following scenario comes true, Rhyperior wins
--- Tyranitar has +6 Defense
--- Rhyperior has used 3 Earthquakes during Tyranitar's 3 turns of sleep, thus Tyranitar is down to about 60% health
--- If Tyranitar's crunch crits and Rhyperior Metal Bursts, Rhyperior wins unless:
------ Tyranitar's crunch critical hit had the lowest roll
or
------ Rhyperior's 3 Earthquakes low rolled substantially
Thanks for coming to my TED talk.
Please notify me if the scenarios with Rhyperior are too likely to happen for this to count as a counter, in which case I have another counter ready as of this moment.
Edit (again):
For Rhyperior, instead of disqualifying me just pack fr*cking leftovers for better chances. Why did I do all the above math.
