it would be pointless to learn match ups or even tactics on dust-loop because they're guide for everything is run away and spam i.d if you play with ragna because its safe, just play your own game and learn from every match you play, and don't let the noobs who use this site frequently that think they're good, tell you how to play any differently, combos you can practice in training whenever you feel, however the only way to ever apply those combos is using and setting them up in matches against people that can actually think and move intelligently, forcing you to learn to be creative in the ways you can incorporate those hits into setups and those setups into combos.
