In my customiser, I put two HP+500, an Attack+1, a Bugstop and a Busterpack. You get 5 attack, 4 speed, 4 charge, and 1000 more HP. For chips, I suggest 2 Recover300, 1 Airhockey3 (for Metalsoul), 2 Metagel (for getting close to smash with Metalsoul), 1 Protoman, 1 Metalman, 1 Bluemoon, 2 Sidebamboo3 (for Woodsoul: charge shot) , 1 Twinfang3, 1 Roll (if you have it) and 2 Barrier200.
P.S.:I have all of these.
