Gonna look over this once more.
*Faces competition with her younger sister, Chansey, who was blessed with the Eviolite, improving her Physical and Special Bulk alike
I told you to say that Chansey has higher overall bulk than Blissey. In fact, just say that Chansey is far better at sponging physical attacks (mix walling) because both of their special bulk are pretty much equal.
*Unlike Chansey, Blissey can hold Leftovers, allowing it to negate the residual damage from Sand and Hail.
Not just the damaging weather, but specifically entry hazards. This is more important to mention because there are times when it's like "2HKO with SR in play unless Leftovers" or whatever.
*Protect should only be used with Wish, as it allows Blissey to receive the Wish and scout the opponent
Mention Leftovers recovery.
*Aromatherapy allows Blissey to clear the team of status
Again, you've ignored my suggestion. It doesn't take a rocket scientist to deduce that Aromatherapy clears status. Mention specifics of what this exactly means. Like I said, it prevents Blissey from being Toxic stalled mainly, and you can mention that it can cleanse a teammate of the commonly seen sleep status so you're not always fighting 5 vs 6 essentially.
*Wish + Softboiled, Softboiled + Aromatherapy, and Wish + Protect are the best three move combinations.
Remove this. Just mention Wish + Protect and Softboiled + Aromatherapy go hand-in-hand in the set comments.
*Toxic allows Blissey to wear down the opponent, and is Blissey's main form of damaging the opponent, and works well with Seismic Toss or Protect.
It doesn't work well with Seismic Toss. Remove.
*Seismic Toss always does 100 damage to the opponent
I appreciate the ignorance once again. I will quote what I wanted to be said here:
"Seismic Toss prevents Blissey from becoming complete setup bait by sweepers (especially most Substitute users trying to avoid Toxic), and allows it to reliably damage the opposition without worrying about its low offenses."
*Flamethrower hits Forretress hard, as well as hitting Venusaur. However, it fails to guarantee a 2HKO on Ferrothorn.
Say that Flamethrower is good against many Steel-types that are immune to Toxic, such as Scizor, Forretress, and Ferrothorn, and how it makes Blissey a great counter to Venusaur.
*Wish can be paired with Softboiled to reduce Blissey's dependence on receiving Wish. Aromatherapy also works better with Softboiled than Wish, as Blissey prefers having more reliable recovery. However, if Blissey needs neither Wish or Aromatherapy, Flamethrower can be used in the second slot in tandem with Seismic Toss.
Remove the bolded part and make it clear that Aromatherapy is always used with Softboiled in the set comments as I've said.
*Anything else that lacks reliable recovery, such as Tyranitar, Heatran, and Rotom-W are good teammates
I don't really like this statement personally. There are far too many Pokemon that fall under this category and pairing Blissey up with Pokemon that don't have recovery is not necessary in the absolute slightest. There are stellar teams out there that don't even have a Wish passer. Instead, you should make a point that Blissey works best on stall and defensive teams because of its Wish passing utility and the fact that its teammates can cover for its shortcomings very reliably. You can conjoin this point with some of the other points probably. In fact, it might be best to make this the first thing you talk about.
Make these changes and I'll look at it again to stamp.
