Unviable, see the VR thread. See also Corv below.
Loses to Thunderbolt, one of Gene's most common moves. Doesn't exactly do anything to it either since Gene is immune to Toxic and special varients don't mind Scalds.
+1 252 SpA Choice Specs Genesect Thunderbolt vs. 252 HP / 4 SpD Toxapex: 306-362 (100.6 - 119%) -- guaranteed OHKO
+1 252 SpA Genesect Thunderbolt vs. 252 HP / 252+ SpD Toxapex: 158-186 (51.9 - 61.1%) -- guaranteed 2HKO after Stealth Rock and Black Sludge recovery
The stereotypical Genesect check, prone to getting worn down by repeated U-turns and hazards due to its lack of reliable recovery, and also very easy for many Pokemon to abuse when given a free switch in from Gene's U-turn, which negates Heatran's main strength of being hard to switch into (nothing likes taking a Magma Storm or Lava Plume with burn, let alone its coverage, but it's pretty slow so not as great on a double switch). A list of such Pokemon include, but are not limited to, Earthquake Mega Gross, Zygarde, Mega Toise, Lando-T, Toxapex, Mega Lop and Greninja. Heatran is also the mon Gene adapts its sets most for, with Hidden Power Ground and Douse Drive Techno Blast being viable to lure and kill/scare off Heatran.
Doesn't like Thunderbolt or Flamethrower/Blaze Kick. Setup bait for Shift Gear sets.
+1 252 SpA Genesect Thunderbolt/Flamethrower vs. 252 HP / 252+ SpD Corviknight: 224-264 (56 - 66%) -- guaranteed 2HKO after Stealth Rock
+1 252 Atk Choice Band Genesect Blaze Kick vs. 252 HP / 0 Def Corviknight: 378-446 (94.5 - 111.5%) -- guaranteed OHKO after Stealth Rock
0 Atk Corviknight Brave Bird vs. 0 HP / 0 Def Genesect: 120-142 (42.4 - 50.1%) -- 91.8% chance to 2HKO after Stealth Rock
Hates Flamethrower and especially Blaze Kick, HP Ground also stings. Setup bait for Shift Gear again.
+1 252 Atk Choice Band Genesect Blaze Kick vs. 248 HP / 0 Def Magearna: 350-412 (96.4 - 113.4%) -- guaranteed OHKO after Stealth Rock
+1 252 Atk Genesect Iron Head vs. 0 HP / 0 Def Magearna: 165-195 (54.8 - 64.7%) -- guaranteed 2HKO after Stealth Rock (who needs prediction, so offensive sets cannot check Gene, so it has to be defensive Magear)
+1 252 SpA Genesect Flamethrower vs. 248 HP / 0 SpD Magearna: 248-292 (68.3 - 80.4%) -- guaranteed 2HKO after Stealth Rock
+1 252 SpA Expert Belt Genesect Hidden Power Ground vs. 248 HP / 160 SpD Magearna: 173-204 (47.6 - 56.1%) -- guaranteed 2HKO after Stealth Rock
...U-turns out of? Or:
+1 252+ SpA Genesect Flamethrower vs. 4 HP / 0 SpD Magnezone: 334-394 (118.4 - 139.7%) -- guaranteed OHKO
You better be very sure it's not scarf, come in on the right move with it having the right boost and hope it doesn't Shift Gear as you come in.
+2 252 Atk Genesect Blaze Kick vs. 4 HP / 4 Def Magnezone: 310-366 (109.9 - 129.7%) -- guaranteed OHKO
Nothing that gets 2HKOed by a Banded Espeed can be your sole Gene check, or you are in deep do-do. Also lacks reliable recovery so gets U-turned on to death, though Boots helps that. Genuinely good mon though, even after Gene gets hopefully banned.
+1 252 Atk Choice Band Genesect Extreme Speed vs. 236 HP / 0 Def Rotom-Heat: 175-206 (58.3 - 68.6%) -- guaranteed 2HKO
+1 252 Atk Genesect U-turn vs. 236 HP / 0 Def Rotom-Heat: 76-90 (25.3 - 30%) -- guaranteed 4HKO
greninja could beat av magearna, and bulu, and most of its checks with the right tech.
The difference here is Greninja has 4MSS, in order to beat its checks it has to give up certain matchups it needs to win or other utility. Greninja also has weaker offensive presence, with no ability to setup. Its weak defensive typing and useless defenses makes it difficult to switch it into battle, and easy to revenge kill with a wide variety of Pokemon. Ash-Greninja makes Gren more dangerous and unpredictable, but it needs certain sacrifices to reach that point. In practice Gren usually cannot beat everything its team would like it to. Genesect has no such issues, being comfortably capable of doing everything its team needs within 4 moves. Its amazing defensive typing makes up for its average bulk and gives it plenty of switch-in opportunities. While they both have U-turn to abuse their checks, Greninja has to give up something like Spikes to run U-turn, while Gene can naturally fit it into its moveset. Having BoltBeam coverage makes Gene's 4th moveslot on its standard set open to everything the team would need, as it hits almost everything in 2 moves. Compare Greninja, who cannot even fit the coverage it would like in 4.
Now stop attacking each person on this thread for their so called "bad arguments" in favour of genesect, we're all here to give our own opinions and votes so once you've done that please just wait for a verdict.
Just trying to actually have discussion and understand the anti-ban arguments (since the pro-ban side has been very well covered at this point). Because there has been multiple people who have just said Do Not Ban without covering why they think that. So... From an outside point of view, everything is leaning towards Ban just because the only real arguments in the thread are for ban. Also, voting hasn't started yet, there will be a separate thread for that in a few days.
