Pikachu, Decidueye(speedy and tank, ) and Lycanroc will be his speedy Pokemon. Rest of them: half attackers-tanks, some low speed etc.You're very good in mathematics(jk). No idea about Ash's final team in Alola, but yes, I want him to catch a Midday Lysanroc, a speedy Pokemon.
And I am not wasting my time on calculating accurate percentage LOL. This is not DBZ power levels
