Imagine you were in a triple battle with 2 Minun and 1 Plusle and you know if they are in a battle together, they get a SP attack increase of 1.5. So what if you have 2 Minun, will Plusle get a SP attack increase of 2.25 or 1.5?
Yes, there are two Minun, so there is a extrea big increase:D. Great for Thunderbolt, those two!!!
