You know an even better one? You can use Ogoun Kyu and Bob Joby! Be sure to not include any other Roots or Uppers, so that your opponent will not expect an attack in the least! I doubt your opponent will figure out that you pilled 12 on Ogoun Kyu... really!
Well yes but it is very risky none the less.. I mean your opp uses say jackie with 3 pillz then you Astrid is dead but I guess this is one of the millions of possibilities of 2 hit Ko.
And don't listen to the haters.. you could state something that is true and it is. So don't waste your energy defending yourself.
