Worth buying the special card?

Is it worth buying the special membership card to get that weapon that comes with it?

Like is it a weapon i would use when im at the top?? or just a nice stepping stone?

 

I'm pretty sure it's purely cosmetic.

 

So there are four tiers:
Tier 1: No requirements
Tier 2: 20 Attack, 20 Magic
Tier 3: 40 Attack, 40 Magic
Tier 4: 40 Attack, 60 Magic

I'd imagine each tier getting fancier looking & a bit better in magic....but its main purpose is to look nice

 

It's for cosmetic use mainly. I don't see a point, other methods are cheaper.

 

You also get a hair style with it, the hair is animated and has electric shocks shooting out from it. It's pretty cool, I'd buy it if I had the spare money.
