Thankyou for those games ^^ They were great!
You bait Zelda really well, which is good. Be careful not to force yourself in your shield - she might grab xD I Usmashed too much =( I played all nooby xD
As for Peach, you must use Utilt OoS - great option. Catch turnips with SH airdodge. Never spindash as approach, only as punishment because I've noticed my nair and bair outprioritise =O
So perhaps go toe to toe with her without attacking her shield or you might get grabbed. Best to SH airdodge around her and take it from there. Peach is one of those characters that's not hard, but different (still challenging for me though xD). Also... if you avoid her fair, she'll have loads of problems kililng =( Never ever shield it! This is key! - roll or run instead always!!!
Hope this helps in anyway ^^ I don't play sonic so I don't know if it might =( But loved those games!
