Us fellow wolf players would love to keep you away from the spamming type wolf(unless necessary in case of the blaster which should be spammed in a controlled progression) so I'll enlighten you on a few of wolf's unique abilites.
Scarring- this is basically after grabbing the edge of a stage, by falling away from the stage with the proper distance and such, immediately pressing over B to cause wolf to fly "through"/"scar" the stage and land in a safe area away from edgeguards(your assured a spike if it hits, of course it's not the best spike).
0 Lag Fair- Basically fairing in conjuction with jumping at the exact time, canceling all of the fair's landing lag. If you Fast fall after this, the lag will not be canceled, and it would be as if you simply did a short hop Fair.
Wall Of Wolf- Utilizing wolf's bair as a tool to edgeguard or restrict your opponents options.
Reflector- This is not to be treated as fox's or falco's reflector, and is used mostly upon the defensive meausre(wolf's reflector contains invicibilty frames where he'll take no damage and immediately "counter" with the reflector stunning your enemy for a small moment). If you ever want to be extremely good with wolf, you'll learn the offensive sides of the reflector as well.
Blaster-Spammable but in moderation. Mix-up your blaster approaches to keep them guessing.
Your best smash..D-smash-nothing said..use it...with a mixture of f-smash as well.
Juggling with Uair- Extremely useful. Learn to use your Uair properly as it is another good move in wolf's array.
Dont forget the Tilts- Of all, f-tilt and d-tilt(if placed correctly trips) are his best tilt's. ALthough Up tilt is a good follow up after a Nair(which has virtually no lag), of course you can follow up with an Up-smash which is just as effective.
Nair- Hands down one of wolf's most versatile moves and the easiest to combo into.
Learn to use his throws properly-His best throw(argueably) is his D-throw. THe other throws are useful as well but it's one of the best.
-Learn to recover properly.
-Read the "Essence Of Wolf"(it'll help with approachs and such and clarify some of the things I stated)
-Read the In depth guide on his reflector(you'll understand the effectiveness of the reflector)
-Watch Aqua's Wolf: expose for new wolf players(it'll relay most of this stuff together)
-Watch vids from the Wolf Video thread and other wolf's in the wolf boards.
That should be all xD, have fun
