Yes while they set-up so they have any chance of damaging Blissey, Blissey can Heal Bell & Fully Heal a teammate with it's titanic Wishes. Such a bad Pokemon.
Blissey is SUPPOSED to be forced out. She's a cleric. If you're using her for anything other than healing others & spreading status, you're probably using her wrong. Seismic Toss is the only offensive presence she needs. It's for breaking subs so she can Toxic/T-Wave & allowing her to do some damage of her own as well. You can run Ice Beam if you think it will help, but Blissey is not a sweeper, she's not even tank. She's a cleric & a wall. She gets in, throws out a Wish, Heal Bell, or Status and gets out as soon as things get hairy, healing a teammate or 2 in the process.
Calm Mind Blissey...jesus...
That's exactly it. I'm NOT using her for anything else other than spreading status and healing others with wish. That's exactly what annoys me about her so much-while she's doing this she's practically inviting enemy pokemon to come in and do whatever the hell they want. A special wall isn't supposed to be forced out by special attackers. And yet, the purely special attacker in subgrowth tangrowth with giga drain and filler kind of...forces her out. I'm not whining about her having no offensive presence. I'm whining about her lack of presence in general. If I wanted to use a pokemon who could pass decently sized wishes, spread status, set up SR, AND do more, I'd just use jirachi.
I made that post earlier when I was in a bad mood. I was fighting an enemy sun team and my opponent was using a Nasty plot Ninetales. I switched to Blissey to put an end to his shenanigans. Ninetales used safe gaurd! It prevents status!
For the record, I am still using blissey. The problem is just that she hasn't been doing anything. She switches into Rotom-W and then switches out immeadiately so I don't hand over any momentum to my opponent as their Scizor, etc switches in. An enemy choice specs politoed? Who am I switching to? Not Blissey, but something that doesn't lose nearly 50% of their hp.
To say that blissey sucks would be an overstatement. Every now and then, when I fight a team that isn't weather offense and actually uses status, she has some value and as I said, using her to wish pass wasn't too bad. But this metagame is extremely unkind to her and it's harder to justify dedicating a team slot to her.
For the record, the only attack I've ever carried on blissey that wasn't siesmic toss was fire blast. Ice beam? I don't think blissey wants to be so kind to excadrill, scizor, ferrothorn, skarmory, etc, etc, etc.
