If you've got a friend, this can be easily boosted with either a Player or Ranked match. Going up against an actual opponent will depend on your skill.
If you're faced with an actual player:
If specials are turned on, it's a great break-out move for combos and grabs alike. You may end up doing more damage than you take as well.
If you're a slower character, use weapons whenever you can to keep your distance.
An opponent using Axel can be a harsh fight, especially if he abuses Grand Upper (a cheap uppercut combo that makes the user near invincible). Attack when he's open and toss weapons at him to discourage him making the approach.
The opponent is invulnerable for a second or two after getting up to give him a chance to fight back. Back off after you've knocked him down to avoid getting hit with some cheap shots.
Play cautiously and take chances when you see them. Good luck.
