I always had a soft spot for her, and she crossed my mind again recently when I was deciding on a more casual deck to build for the local metagame
Cards that care about modified creatures work great with Me, with Kodama of the West Tree giving Me trample and helping you land ramp when she does combat damage, and Akki Battle Squad giving you another attack step, which will also activate Mes beginning of combat trigger for more counters
Why exactly this mechanic didn't get the success that it possibly could've is a bit harder to figure out, but it could be because most people just simply didn't care when there's so few cards that use it, and none of which being particularly powerful enough to leave a mark on the game
