As a Wii Fit Trainer main how do I deal with Samus, especially Spammers, I try using my own projectiles but they dont work and I just...cant seem to punish her roll.
Your soccerballs won't help you. At all. They'll recoshe off of all her projectiles. Only use it for edge guarding. speaking of which, her up-special is invincible so don't get in it's way unless you wanna risk being stage spiked.
Her missiles are easy to take car of...in writing. You can easily roll past them but will easily be read (not that it should be too big of a problem with Samus though. All of her projectiles have some decently long ending lag). My personal favorite way to get rid of them is to hit the missiles with any melee move. It takes great timing, but doing so will leave you unscathed by the now destroyed missile. It also shows how capable you are and might scare your opponent.
I suggest charging your sun-salutation to the max and holding on to it as bait for the Charge shot. Do NOT use the sun-Salutation to defend against the Charge shot. Having your SunS fully charged will scare the Samus, making them succeptable to mind-games. Use this move in tangent with deep-breathing but only for the kill. Edge guarding against samus is really difficult so you'll have to smash them into the blast-zone.
Things you have the advantage in:
1. Her jab. Your jab is great for killing and is quick and rather safe at the beginning. The big thing however is that Samus's jab1 is UNSAFE on hit. If you are still on the ground when you get hit by the first jab and are close enough for your own jab, SPAM A. It will more than likely beat her second jab. Meaning a free pitfall effect for you!
2. Great speed and less commitment. When you finally get in close, go all out. If they have a tendency to roll away, keep calm and try to read where with whatever move will hit but is safe on whiff (incase you mis-predicted their direction). If you choose right then keep up the pressure. Spammers are unlikely to be great at using Samus effectively up close. If you choose the wrong direction, then would be a good time to use SunS as a means of punishing. Don't worry about charging it. You can easily charge the SunS to full while the spammer charges their own CS or spams missiles on the other side of the stage safely.
Another thing about your speed and air mobility. Bait and bait some more. most of Samus's moves are punishable if whiffed. Especially the tether.
About her roll. I don't know how fast WFT's walk is but Marth is great at punishing rolls after walking. Walk towards them to bait the roll, then after deciding where they will be, STRIKE HARD. If you don't feel comfortable punishing with melee moves, use SunS to do so. Luckily for you, Samus's roll is especially slow though it travels farther than most. Just bait a roll and punish. Most Spammers will always roll towards the opposite side of the stage after you corner them.
One last thing about Samus:
She outranges most of your moves. A good samus will use her tilts and Zair effectively. But you're not going against good Samus', are you?
In summary, don't use the soccer balls. Keep SunS fully charged for punishing rolls and whiffs and killing. Do not use to defend against CS. Use your great speed for that. Also, try to use it for mind-games. Bait grabs if they are grab hungry. Missiles are easily defeated with melee moves and rolling (I believe WFT's nair covers a lot of space so use that if I'm not mistaken). Expect and predict rolls. Punish them heavily with combos and keeping the pressure with melee moves. Samus is easily combo-able and all spammers deserve to die! Do not Edge guard samus as WFT. Use Deep-breathing to kill.
Notice that this is specifically meant for Samus spammers, not good players.
Best of luck and have a good night! hope this helped!
(if you would like to practice against a samus I am available soon on the 3ds. No wiiu for now)
If all else fails, choose a secondary that checks Samus spammers. (ideally: Link, Sonic, Link, diddy, Link, Link, Link, Capt.
Falcon Link, MegaMan, Fox, Falco, Link, Toon Link, Bowser Jr, sheik. All of these characters have a spammable move that deals with spammers or are just too fast for spammers to handle. Link doesn't do any of these. He has his shield and bombs to cover rolls, TEH BAIN OF ALL TEH SP@MMARS!!)
