Specifically what is a healthy % of the metagame for a deck or archetype to have in legacy? In vintage 25% is way too much, this is different from type two or block.
I have a feeling that legacy is a format where the top 8 of major tournaments is going to regularly be made up of 2-4 copies of the same deck, and that this will always be the case regardless of cards being printed or decks being neutered.
With that for a base, what do you feel format dominance is in legacy?
