Lower percent (on dreamland side platforms/opponent is near the middle of the platform):
1. Lightly throw bomb up and throw back with bomb damage (back throw does 2% more damage than forward throw)
2. Throw bomb from above and fast fall uair/attack (bomb does most damage when thrown from above)
3. Combo without bomb
4. Throw a bomb over opponent, drop through the platform and uair, bomb hits, then jump and attack
5. Throw a bomb high up next to opponent (while standing on the side closest to the edge of the stage), take out another bomb (from same position), jump over the opponent above the other side and throw that bomb down (or run off the platform towards the middle of the stage and throw the bomb backwards), 2nd bomb throw hits, 1st bomb thrown hits, fall uair/attack if 2nd bomb was thrown from air OR jump uair/attack if you ran off platform and threw bomb backwards
6. Trying to do something with the boomerang seems risky, you could catch it and it'll MESS YOU UP. Bombs do more damage too I think.
Higher percent (on dreamland side platform/opponent is near the middle of the platform):
1. Strong attack/bomb+throw
2. Up tilt/uair/down tilt to strong attack
3. Throw bomb from above and strong attack OR uair/nair/first hit bair to strong attack
If you give a good idea I'll add it to the list.
