PPMD used dash forward to wavedash back to fake approaches, combos for stage positioning and early edgeguards instead of % or possible 0 to death. He spaces short hop turnaround lazers with dash dances and wavedashes and likes to poke shild with jab. His game is based around taking stage position and pushing the enemy in to a corner by taking away space and options with hitboxes and movement -> neutral on the ground second to none.
Westballz often plays the most defensive out of the 3, uses bair and uptilts to put up a wall. His combos lead to alot %, but he sometimes struggles to finish them or uses options to make them longer instead of going for the kill, hes still the only one of them that 0-death often (especially on FD). You will often see him punish get up attack optimal by using CC to fsmash. He also likes to do waveland into enemys and shine to surprise them (for ex, on FD).
Mango is the king of mixups. He does the same thing 10 times with a different timing each instance, its insane.
