>>51574763leaks coming in through the grapevine. Ash and Leon will tie in a 6 v 6. Ash uses his Journeys team, Leon will use his usual team without Eternatus.
However, since it's a tie, we will get a 4th episode with the tiebreaker AFTER some Project Mew episodes.
In the tiebreaker ep, Leon will use Eternatus. Ash will use Greninja. Since Project Mew is over, Goh will be there at the stands to witness AG vs Eternamax Eternatus.
Ash wins.
