What's your strategy for Ruby and Emerald?

[GypsyElder]

I just realized I only killed Ruby once in my life lol. I started a new game and I'm just playing with different strategies for them since I didn't really have one the first time I killed him.

I'm not sure if this is already a strategy but I just found a really easy way to beat Emerald. All you need is Mime on Cloud, KoTR paired with HP absorb and W-Item on another person and underwater on the third person and about 4 hero drinks. Let the person with underwater die, (make sure that person is in the middle) use W-Item for 2 hero drinks on Cloud then have Cloud use the rest of them on himself. Have the person with KoTR cast it. All you do for the rest of the time is mime. Oh and everyone should have Sprint Shoes.

What are your strategies?

EDIT: OMG I'm an idiot I can kill Ruby now wooo! why is it that I can paralyze him? hahahah
