Actually Nayban that doesn't work. When you Ninjutsu in the second Shinobi after the first one dealt its combat damage, it would be too late for the second Shinobi to deal combat damage and bounce another creature. So there is no continuous bounce loop.
The most you could do is up to 2 times, having one Shinobi attacking and with first strike so that he would deal first strike combat damage and afterward during the first strike combat step, you Ninjutsu in the second Mistblade and he would be in play and attacking before the normal combat damage step, which will be in time for him to deal his own combat damage and bounce a second creature.

This card is easily one of the strongest cards I have. If you can manage to get this past an opponents defenses, and have a second one in your hand, you can use Ninjutsu to bounce them back and forth, returning every creature an opponent controls. As for its Damage being low, just play Ronin Warclub or something else that has "Whenever a creature enters the battlefield under your control, attach Ronin Warclub to that creature." and you wil be doing 3 damage every time you bounce one.

I have a ninja deck and I've never liked this guy much. For all the work required to ninja something out, you really want a better effect than just an unsummon, especially since you generally want multiple ninja hits after a ninja comes into play, which often means casting some kind of removal effect BEFORE you attack.

The master Unsummoner himself. A must-have in a Ninja deck.
