Roots have Jeena, Rico, Noodile Cr, Nahi Cr, Craho and Yookie, this also give you stop opp: ability.
Or if you want more damage Fang pi clang has: Nakata, Xia Leming, Yu Mei, Zhu Tang, Ralph and Sayura.
P.s the cards mentioned above are not in order of usefull ness.
1)I'd reccomend piranas to go along with vortex (assuming you like pill-manip style decks).
2) When you can afford some of the higher-power/dam vortex cards *cough, dregn*, then you should start focusing on 2hko's
3) Cards like akhab, tyd, and both hawkins versions are pretty deadly when paired alongside vortex (as they really force your opp to choose who to pill).
