[Behold, one and all! The greatest Tournament in the history of Pokemon!]

I'm Curious... Who had the lowest win rate of all trainers? Was there any trainer who lost all fights?

[Sewing the Seeds]

So they get the boost (and the item is consumed) when a field of that category is activated, does the boost change when the field change from one field to another (for example super heated and burning, to me they make sense to be in the same group) or they keep the boost even after the original field is destroyed?

I think the most logical would be keeping the boost but the most fun would be an ever changing boost depending on the field (but that would be better for a non consumable hold item or if it produces an aura or similar for the pokemon)

Anyway it seems those little seed would be a nightmare or a blessing... Nice work
