For the text it's all about using as little of your own text a possible and as much premade text as possible. If you're making a street fighter tag then use the street fighter logo, if you're making a 24 tag than use the 24 logo. After that its all about masking the logos and adding some lighting and some glow onto layers above that and then masking them in different ways which you think look good. Check out BLANE's Pandorum tag to see what I mean.
