The clean sequence is the whole appeal: swing with an unblocked evasive creature, and after blocks are declared, return it to hand to bring the Ninja down tapped and attacking with a bounce trigger already on the stack. That folds two things into one attack step. The returned attacker goes home to reload whatever value it carried (its own enter trigger, in many cases), a fresh 2/2 slots into combat, and the bounce peels back a creature your opponent just spent a turn committing. Because Ninjutsu fires only after blockers are declared, the bounce cannot un-assign a block or push a stalled attacker through: what it can do is send a blocker that got assigned to nothing back to hand, unwind a creature your opponent held in reserve, or clear a body before your next attack step, all at instant speed. Making the bounce "up to one target" is the concession that saves the card against an empty board: with nothing worth returning, it simply arrives as a body rather than forcing you to reset one of your own permanents. The design axis is timing more than rate. Entering from an activated ability at instant speed sidesteps the sorcery-speed exposure of hard-casting a four-drop into an open board, and it lets the bounce answer whatever the board looks like in the middle of combat rather than committing to it a turn ahead.
