>>32287543It wouldn't. Three main reasons why.
1) Mixed offence is shit, you're wasting a boost in one stat unlike eviolite.
2) The evos will always be better with a choice band/specs or life orb. They're faster (most important) and bulkier (less important) and have better damage output with items with easily worked around drawbacks. Unlike eviolite, where there's either no alternative or the drawback is so unworkable (assault vest) you may as well not bother.
3) Prevos tend to lack the good offensive moves their evos have, where on the defensive side prevos rarely don't have the support moves their evos have.
Exception in sneasel, kadabra, haunter, scyther and rhydon all being more viable in lower tiers. Nothing relevant to OU or even UU.
