Only caring about permanent spells is quite strange wording for a card that cares about creature types, and likely a way of cleaning up rules questions and potential confusion such as does Aquitects Will trigger Deeproot Waters? (It does, by the way)
Originally issued to Wizards of the Coast employees at the time, these rare Pokmon cards were not supposed to make it onto the collector market
To sell Pokmon cards on TCGplayer, simply list your cards on the TCGplayer marketplace, set your prices, and wait for potential buyers to purchase them
You only want 1-3 per list, usually on the lower end of that range
Open packs, have fun, and stop when you want to stop
