Leon winning to ash?

Leon proposed to use all mechanics in the battle which yeah makes for a good unpredictable battle but I don’t think he would give that much of an advantage to a competitor so I think his strategy coming in is to dynamax (charizard, as he did) and terrastelize. Now hear me out, Cinderace has libero and is now immune to pikachus thunderbolt and his electroweb meaning that only iron tail and quick attack can affect it, so I think Leon will terrastelize Cinderace to become a ghost type and therefore sweep pikachu. This will lead ash to go to paldea to learn about the mechanic and master it just like Leon, meaning that Leon’s character isn’t wasted and can still come back. So everyone saying that if ash loses then Leon had no point at all being his goal, but ash can still try to defeat Leon and Leon can still be his goal
