Yoda mythic

I used (g11) zeta qui gon jinn lead, (g12) general kenobi, (g11) aayla secura, (g11) Ezra, and (g11) gm yoda.
Kill order was sith assassin, then nihilus, maul, and sidious. It was about aayla getting stuns and yoda reducing turn meter at the right time.
Very surprised there was no achievement for this mythic.
