the candy and choclate when you see them you gota kinda just stay put or pull back or else vs a good player you'll get countered for that. That is one of the mistakes many faust players (myself included) have come across. His rush down game usually consist of an item aiding him.
Hammer and coin is when I like to do most of the rush becuase if your opponent hits you youve got that as a means of bailing you our or if theyre blocking it just adds more pressur.
small guys (robo -ky, pot, mini faust ) - Alot of smart Faust players wait for them to land and thrown another item out after they land every now and then because it helps controle the space and if you get another small guy comming down it puts you in a very strong position cuz ur able to controle a big portion of the screen.
Bomb - If you have tension one of the sheningans I like to use is the door tricks, if you can FRC the backdoor and command grab immediately they will bounce off the explosion and you can combo after. (this of coures works only at the right distance)
If your opponent jumps you can use the 214k door and catch them in the air rc/frc and watever floats your boat after.
Poison - A nice way to shield urself and throw another item out safely. you can command grab your oponent on wake up if the poison is on top or close to them (some frame trap glitch there). most of them will usually be blocking at this point anyways and try to always get as much damage as possible done when theyre poisoned.
Meteor - Yea as stated above you can do a command grab set up if theyre scared but that doesnt really work to much these days but still another weapon is your arsenal. Metor coves a majority of the screen alot of player will just simply jump fd cuz its safe to do so so try to air grab bait them when possible.
Pan - kind similar to coin and hammer i suppose, if it hits your opponent when theyre standing learn to react quickly and use the scapple pull in.
