lol i play all three of those as neutrals.... :X
ok done testing pictochat for purple uthrow, idk if freshness matters in training or not but i made sure my uthrows were all fresh before i tested them. (i tested this on mario btw, so it might work lower/higher percents on others)
If you purple uthrow into the pirhana plant thing it will kill them at 70 percent as opposed to the 115ish that it normally takes on picto, this is most likely something that you can't di to survive because it throws them up when hit by the plant, and they will probably start di-ing left, but then it sends them pretty much at a perpendicular angle into the top of the screen and they die :D
It's crazy situational, hard to pull off, and there are generally way better options, but its super flashy and really fun haha
