Guide to becoming a better Smasher
1.
Shield: Use it. This is the most important tool in your arsenal. Not only does it provide protection from all attacks, but it can be cancelled into a jump, up-special, or roll in the event that it weakens or someone tries to grab you. Don't just aimlessly put it up though, use it out of a dash/run for best results.
2. Roll. Despite having a risk factor in it, rolls are a very reliable way of escaping pressure and getting out of trouble. They may not be the most efficient way under all circumstances, but under non-tournament settings, it works wonders. Don't overuse it though, or people will start to catch on and punish you.
3. Jump evasively. This is arguable a more effective form of dodging then rolling, as you not only get full control of your momentum, but also have to option to attack. To use your jump defensively, either jump over the opponent or away from them, if they make a mistake in trying to hit you, then punish them!
4. Practice Strings. Every character in the game has at least one true combo or string in their arsenal. Experiment with different characters and test the % ranges for these strings in order to maximize damage output.
5. Smash Attacks. Another important tool. these attacks are not only fast, but powerful as well, use them when your opponent's % gets high (80%+ will suffice) to finish them off!
6. Special Moves. Each character has a different set of custom moves of which all have different properties and applications. Study your characters' special moves in Training Mode and Online in order to get the most optimal results from them. Just make sure to to overuse them or you'll get punished!
7. K.O. Setups. This one intertwines with 4. certain characters have strings that they can perform at high %s to finish off a stock for their opponent. Experiment with your character to see if they have one. Some characters like Ness may sacrifice the conventional K.O. setups for a kill throw instead, in this case, his Back-Throw.
8. Keep Practicing! Now that you've learned all of the essential information for competitive smash, you now have a basis on which you can improve! Spend lots of time experimenting and testing out new techniques or tactics, whilst you work your way to the top!
