matchup i play alot, your nair goes through samus missles (remember that)
try as hard as you can to keep the samus from charging up, make sure you keep constant bomb pressure on her, make her scared to come out of her shield, then when you can predict her coming out of her shield, make sure your foot is in her face (it always ends well for you
) and at the higher percentages your best kill moves are dsmash and dair (uair works also, just not as strong as a move)
absolutely do not get bounced by her missles, when she has the blast charged up, be wary. again, keep constant projectiles raining down on her (i know its tough when she's always shooting those gay missles) any spare moment should be used to take out a bomb. remember to use mind games with your bombs, throw them straight up (your opponent most likely WILL get fooled by this and give you the chance you need to dair)
if you cannot shuffle a dair your in lots of trouble and making the match alot harder on yourself. do not sit back in your shield, always be mobile making samus's life miserable
