Hmmm...I don't know if this works all the time, but I noticed that if you do a forward grab on marth then do a dash down grab, you can just turn around, do the dash forward grab again and do a down grab which racks up damage nicely. You can actually pull this little trick off about three times if done right, but by then they have too much damage and usually travel out too far to catch them in mid-air and their stun lag is gone. I did this on practice mode if you wanted to know. But yeah, I don't know if this little chain grab I found works on all characters, but I thought this might be atleast a little helpful. Besides, I think the first two chain grabs should work right, plus it's not like they will see it coming. tell me what you think.
