Both Stunfisk and Whiscash resist Flash Cannon and take neutral from Focus Blast.
Correct me if I'm wrong, but I think Stunfisk is bulkier than Whiscash. But Whishcash is definitely the wayyyyyyy budget option.
Budget wise yes, while whicash only weakness is grass, so i lose to a match up being complacent, suay suay really grass,
What can be done is swap in early, charge up
Becos if its grass behind, fire off blizzard i think pratically ohko
Regarding flash cannon and fb
I suppose ur talking about registeel
Chances are they will fire only FC, beh hu for FB
Mudbois will just mud until they bth......
Idm investing a lucky stunfisk for the fact is cheap, candies is an issue, not sd thou
