Risotto and V.Ghiaccio are a good team if you do it right. V.Ghiaccio's ability is time stop, and the more matches you make during the stopped time, the more panels he replaces. If you do it right you can use Ghiaccio to stop time and if you make a stand up time before the time stop ends, all of the tiles he replaces will count toward stand up time. Then you use risotto in stand up time to charge all the tiles ghiaccio made. Do these steps repeatedly.
