Sanger Zonvolt still has a solid point in that no Pokémon likes being statused, aside from obvious exceptions like Poison Heal Gliscor. While Aegislash has no means of recovery and, as such, burn is a nuisance to it, that doesn't stop it from blasting shit with Shadow Ball. I'd also like to add that Aegislash still reverts to Shield Forme
even when fully paralyzed on a turn, so it can at least switch to its 150/150 defenses to take an incoming hit. Looking at the Pokémon you listed:
Jirachi isn't doing shit to Aegi and there is still a chance for the sword to successfully execute King's Shield, nerfing Jirachi's Attack if it were to spam Iron Head or use Fire Punch, since p much any physical move Jirachi learns makes contact. Either that or it could just Shadow Ball Jirachi's ass from the get-go and leave the Wish Pokémon crippled.
Gardevoir can deter Aegislash with Shadow Ball, but that sacrifices coverage or utility and leaves it easily checked by Aegislash's teammates if Aegi itself cannot deal with it. Again, getting burned doesn't stop it from blasting Mega Gardevoir with its own Shadow Ball and then follow up with Shadow Sneak, were it to run that.
Slowbro's Scald, once again, can leave Aegislash burned, but there's still a
70% chance of that
not happening. Meanwhile, it's OHKOed by Shadow Ball after SR damage. Checkmate.
Chansey is
walled by Aegislash despite being able to paralyze the sword. If it already has a Substitute up, it's literally not doing a single thing to Aegislash while Aegi itself just stalls the shit out of Chansey.
Starmie can 2HKO with Hydro Pump, but it's an inaccurate move and you clearly didn't mention its low accuracy, potentially giving Aegislash a free switch. I've gone over burns too much by this point, it won't prevent Aegislash from sniping Starmie with Shadow Ball.
The points made b
y Viridi and
firehusky before me definitely hold true as well. You're regarding the situation with tunnel vision, only taking into account the chances that Aegislash
will be haxxed and
will suffer from its effects, without taking into account any situation where the hax
won't apply.
On a final note, for the love of Primal Groudon, stop acting like a little smartass and show some mature behavior in a proper conversation. Telling others they 'understand nothing' while bringing up mostly completely invalid points is disgustingly hypocritical.
