Yoshi/Law is my main team. Both of the characters build meter very good. And can do some interesting tag combos.
Starting with Yoshi: Windmill, tag, (Law) hp, shaolin spin kicks, tag, (Yoshi) (mk) windmill, tag, (Law) hp, shaolin spin kicks, tag, (yoshi) hp+hk (raw launcher), (Law) finishes the juggle combo.
As both Yoshi and Law build alot of meter you should already have built up a new bar during the combo, leaving you with one meter after the combo.
You don’t need to tag that many times during the combo tho just felt like writing it.you can also skip going into raw launcher and go right into a standing combo, the possibilities is many.
You can also do it starting with Law. Law also have the most damaging combos of the 2 so I normaly end them with him.
