Matchup Summary (Win Condition and Game Plan)
Mewtwo can disrupt spacing with mobility and Shadow Ball, but the matchup still pays well for Simon because Mewtwo is light, tall, and vulnerable across the tail, so Simon’s long normals and projectiles convert cleanly when they connect. The game plan is to slow Mewtwo’s sideways drift with Cross, keep fair and bair at tipper range, and cover jump-outs with Axe or uptilt until the interaction is pushed to the ledge. Mewtwo’s fair and dtilt are not always easy to punish on shield, but forward tilt, up tilt, dash attack, and Disable all leave real shield-punish windows for Up B or grab, so Simon can break close-range pressure if he stays disciplined. Do not overchase offstage just because Mewtwo is light. Teleport and aerial drift can slip past deep edgeguards, while Simon’s ledgetraps with Holy Water, fair, and anti-air Up B are the more reliable way to finish stocks.

Win Condition Checklist
- Show Cross often enough to interrupt lateral drift and deny free Shadow Ball charge while holding fair tipper range
- Cover high jumps and fade-backs with Axe and uptilt so Mewtwo gets forced toward the ledge instead of resetting center
- Punish forward tilt, up tilt, dash attack, and Down B on shield with Up B or grab instead of scrambling after blocked fair pressure
- Finish stocks through ledgetraps with Holy Water, fair, bair, and anti-air Up B rather than betting on a single center-stage read
Actions to Avoid
- Giving up stage too early out of fear of Shadow Ball and letting Mewtwo retake the pace for free
- Chasing too far offstage and giving Mewtwo room to bypass you with Teleport or swing back with aerials
- Swinging raw forward smash or Axe at close range and feeding Mewtwo easy whiff punishes from dtilt or fair
