This is "unique" for me because I've never seen anybody do it in about 400 battles;
In Triples I use a Typhlosion who is Choice Scarf'd up and I only use Heat Wave. People assume he's going to Erupt, so they often scramble to use weaker priority moves on him or less-than-effective moves to lower his health. Often, they get him into the Blaze range (1.5x) and with Drought (and Helping Hand if it's available) it can kill all three opponents usually.
