I. Hate. Wording.
Can someone give TPCi some English lessons or something? Succinctness is key guys. KEY.
Haha but really, this was quite fun.
I've grown quite attached to my little Castform after spending 3 days milling through the TCGDex on pokemon.com to look for cards with appropriate wording. I found a bunch of them, references will be at the bottom, but it was tedious.
ANYWAY, Castform. Chose it for the UK because our weather is as temperamental as weather can get. I chose the specific dex entry I did because Britain can get extremely humid, which makes me being sensitive to humidity very annoying :U. Also Castform was made at a research lab in Hoenn and Britain is one of the leading technology countries in the world for some reason. Probably because our Government values money over human life or something.
The basic idea behind the card is versatility! But of course, the versatility would require 4 of the 60 cards to be used up just for two different kinds of energy, though I suppose it would only be 2 extra cards if it were being run in a [W] or [R] deck to start with. Meteorology Ball is quite strong on paper, but realistically it can hit for a maximum 80 base damage if Castform also wants to make use of Climate Change, so I don't think it's too powerful. As far as I understand it, 100 base power isn't particularly broken either, even on a not-EX Pokémon. Forecast is just there to help make the most use of Climate Change and of Meteorology Ball. Castform's HP is quite high for a Castform, but from looking through the dex it looked about standard on a basic Pokémon that can actually dish out a bit of damage.
I'm not sure how viable Weather Forecast will really be because it does involve discarding a Energy card from your hand. Naturally there are I think some trainer or item cards which fish Energy cards out of the discard pile, but that also means you have to run those item or trainer cards in your deck too just for Castform, and this thing definitely doesn't look good enough to be the glue of a deck to me.
Wording-wise I'd like to justify my Climate Change ability not just saying "this Pokémon becomes x type" because then I think it would be able to make use of stuff like Splash Energy? That'd be exploitable by Meteorology Ball. And I didn't want to stipulate "basic" Energy in Meteorology Ball because I couldn't find a reference dictating where to stick the word "basic" into the sentence and didn't wanna get it wrong, so I opted for the long-hand on the Climate Change instead. Plus, I'm not entirely sure what exactly "this Pokemon becomes x type" necessarily does, and whether my weaknesses and resistances are standard or not.
And yes, both "Forecast" and "Weather Ball" were taken by earlier Castform. They were the original names of "Weather Forecast" and "Meteorology Ball", respectively. I am sad they were taken.
Finally, no weaknesses or resistances is certainly an interesting choice, but I didn't think it was very true to Castform to have a fighting weakness when it was in different weather forms, so I opted for this instead. I get that this can make it a decently strong basic (though 100 power isn't a lot, and it only has 110 HP anyway) without a weakness to off it sooner, but the impression of the metagame I get right now is that EXs can deal 110 HP in their sleep. And yes, it is possible to have no weaknesses or resistances, because Sableye did it.
