Johnznothere has it correct! w00, ezness!!
1. Name=MAGIKarp
2. Flavor Text on Base Set Magikarp="In the distant past, it was much stronger than it's horribly weak descendants that exist today".
3. In G/S/C(or just one of those, kinda forgot...), they gave Magikarp Flail, but since it was at lvl 30, it was never used since anybody with a brain would have a gyrados by then.
Congrats.
