I clicked alternate forme, selected Tornadus-T and then when I exit the pokedex window it stays as Tornadus' regular forme. This new PO gives me a goddamn headache.
Click the regular Tornadus forme. Click and make it Tornadus-T, then before you close that window click "Change species". Save your team and you should have Tornadus-T now.
Hi dear i also have this question if you ever get any answers than also contact me here i will wait for your response?
Do exactly what was said above. On v2 while in the teambuilder click on the picture of the Pokemon and a window will pop up. There should be an option to make it shiny, change its form if possible, and change its species. Click change species and click outside of the little pop up window to close it. After you are done editing the team click on the tab that said Trainer Home. After that click on the little floppy dick icon to save your team. If you are still on v1 under the picture of the Pokemon in Teambuilder there is a tab called Advanced. It might be under there but dont hold me to it. In fact Im not sure if v1 supports the Therians at all.
