>>56891137Don't forget to take into account Round 2 and how bullshit it can be.
If you plan on beating Stadium with just rentals you might need to do some research ahead of time on specific problematic trainers and see common strategies.
And it's like
>>56891162 pointed out. A lot of things were changed that would make usual gen 1 strats different and that also needs to be taken into account.
When picking rentals, always keep in mind that lower evos have the better moves while the full evos tend to get worst options. Including with fully evolved pokemon having 0 DVs (if i remember correctly.)
Stadium is a very very odd time but can be rewarding if you are willing to take the time and work with team comp per cup difficulty and which round you are on.
