Hey Colorless Green,
Could you do a verification on Malignant Balls for me for Gold and Plat. It doesn't do as well in Plat as it once did... but in gold last I check it was still doing over 75% WR, my last 25 games with it today were 20W 5L 16 EMs, 14 TTW, 4 Spins... I don't think anyone ever did a 1.32 Arena study on it.
