so here is a question for the TAM; am i able to trade over a ball to catch Eternatus in? it would only be used on him; i only ask this as the game would just give you a random ball if you don't have one so i wanna see if that would invalid the run. if you wanna know which ball it would be fast ball. If it does then i won't trade one over; its just a question.

Hi there! So, the answer would probably be "sure why not what's the harm", however the only way to trade in a fast ball (or any ball, or any item in general) would be through trading with another player, which is not allowed. If items could be transferred through Pokemon Home, then sure that would be fine, but since you'd have to use the internet and trade with a separate account/console, that would be against our rules. Sorry about that, thank you for asking!
