Actually, yeah it should. Jokes aside, I 2 hit ko'd a torkoal in sun. WITHOUT Tera, that shit hit hard.
I remember using it in previous gens lower tiers too as a great Sticky Webs absuser. Ribombee was faster, but Araquanid was bulkier by a long shot and very threatening. It with Hoopa-C and several priority abusers actually got me pretty high on the Gen 7 UU ladder. Imagine if Dracovish could set up its own Sticky Webs.
Anyways, elaborating on point about Psychic Noise
-When Psychic deals less than 37.5% damage to the opponent holding Leftovers, it will outdamaged by Psychic Noise in 1 turn as Psychic Noise would deal 31.25% and Leftovers would heal off that damage.
-When Psychic deals less than 75% damage and either the opponent is being doubled healed with Leftovers+Grassy Terrain or Poison Heal, Psychic Noise will deal 62.5% damage which will outdamage Psychic thanks to it blocking healing.
—Should be noted you 2HKO at that point, so it’d need to be around 50% for the blocking of leftovers/grassy/poison heal to matter. Still favors Noise as it blocks Recover moves.
-When using Psychic Noise, you also block the healing effect Drain moves have such as Bitter Blade, Horn Leech, Drain Punch, and Drain Kiss.
Pros:
-Can make wallbreaking much easier for Psychic Types that learn it as Pokemon switching in can’t recover
-At some damage thresholds you actually do more effective damage
-You can switch out after using it without giving your opponent a free heal via recover or roost
-Pairs wonderfully with Grassy Terrain as you can hog all the healing for your team and pairs nicely with Burns and Poison
-Being Sound, you bypass Sub, are affected by Liquid Voice, and you activate Throat Spray when using it
Cons:
-It has less raw power, which can sometimes rob you out of an OHKO or 2HKO on a Pokemon that otherwise doesn’t heal itself
-At other thresholds you will do less damage definitely (ie. Psychic does like 57% while Noise will do 47.5%, so Psychic is always a 2HKO and Noise is a 3HKO) (It’s so small it REALLY doesn’t matter but is a downside anyways)
-Pairs poorly with Knock Off as Knock Off will Knock off Leftovers and nullify that positive basically
-Being Sound, you are affected by Liquid Voice (meaning you now compete with Hydro Pumps), Pokemon with Soundproof are immune to your moves, Punk Rock will halve your damage, and Throat Chop blocks your move entirely
-Shield Dust blocks this effect and so will Sheer Force (which only matters on Braviary and in OMs)
Something about the Psychic Noise Discourse: how many Draining Kiss or other Drain-move users are there in OU? Apparently the Heal Block effect extends to these moves flat out not being clickable as opposed to hitting without healing. Are there any major Pokemon who this interaction would affect (effectively being Disable on one of their attacking options)?
It won’t prevent the moves from being used, but will prevent them from healing.
Which actually has me thinking. Does Triage get priority if under Heal Block effect?
