Regarding in battle Mega-Evolution and the legitimacy of mono-type teams?

Will a Pokemon’s mega-evolution’s type allow its use in an otherwise illegitimate mono-type team, as long as said Pokemon mega-evolves when it is first used in battle?

^ That’s what I wanted to ask, but it reached the character limit

I guess this kind of relates to my other monotype question, and it might be little early to ask this, but I wanted to remember to ask. If such rules have been defined yet, will I be able to say carry an Ampharos on a Mono-Dragon team, as long as I mega-evolve said Ampharos as soon as it is in battle? Any knowledge on this matter is appreciated, as is speculation, as long as the latter is said to be speculation. Thank you.

Im going to answer withNO, you wouldnt be able to use the Mega-Ampharos in a dragon team. Heres why:

In the current OU Monotype metagame, Pokemon that have form changes that change it type arnt allowed to be placed into that type. Like previously stated Darmanintan couldnt be used in a Psychic team even though Zen Mode made it part Psychic. The same could be said about Melloeta, because when it changes forms it changes from a Normal/Psychic type to a Normal/Fighting type, yet it still cant be used in a Fighting team. Based on examples like that its safe to say that the Mega-Evolutions will be no exception to this rule.Again this is just my guess from the past examples set.
