Oh ya and if you could tell me how to beet #50 event match for Super Smash..

Event Match #50: Final Destination Match
Character: I suggest Ganondorf for this one
Opponents: Master Hand & Crazy Hand (each with 300HP)
Arena: Final Destination
It helps if you know their attacks - they usually have a signal that lets you know what they're about to do so you can dodge it. Also, focus on one hand at a time - once one's gone, it's easy to beat the other. Lastly, use Ganondorf's smash up+A attack - it's the strongest and most effective against the Hands!

There's only 25 Characters, so you can't fill those 2 corner spots - that means no Giga Bowser or Crazy Hand unfortunately.

The last two spots are Giga Bowser and Toad. Giga Bowser, just beat Adventure mode on Very Hard with one stock, no continues, under 18 minutes and as Kirby. At the end, have Kirby suck up Giga Bowser and keep the ability until the end of the battle when all three bosses are defeated(Master Hand, Crazy Hand and Giga Bowser). Toad, all you have to do is go through Classic and hit all the credits then just go through Adventure as any character.
