Fallen Shinobi — ruling 1

Fallen Shinobi's triggered ability doesn't change when you can play the exiled cards. For example, if a sorcery card is exiled, you can cast it only during your main phase when the stack is empty. If a land card is exiled, you can play it only during your main phase and only if you have an available land play remaining.

Fallen Shinobi — ruling 2

Casting an exiled card causes it to leave exile. You can't cast it multiple times.

Fallen Shinobi — ruling 3

Any cards you don't cast will remain in exile.

Fallen Shinobi — ruling 4

The ninjutsu ability can be activated only after blockers have been declared. Before then, attacking creatures are neither blocked nor unblocked.

Fallen Shinobi — ruling 5

As you activate a ninjutsu ability, you reveal the Ninja card in your hand and return the attacking creature. The Ninja isn't put onto the battlefield until the ability resolves. If it leaves your hand before then, it won't enter the battlefield at all.

Fallen Shinobi — ruling 6

The creature with ninjutsu enters the battlefield attacking the same player or planeswalker that the returned creature was attacking. This is a rule specific to ninjutsu; in other cases, when a creature is put onto the battlefield attacking, that creature's controller chooses which player or planeswalker it's attacking.

Fallen Shinobi — ruling 7

Although the Ninja is attacking, it was never declared as an attacking creature (for purposes of abilities that trigger whenever a creature attacks, for example).

Fallen Shinobi — ruling 8

The ninjutsu ability can be activated during the declare blockers step, combat damage step, or end of combat step. If you wait until after the declare blockers step, because all combat damage is dealt at once, the Ninja won't normally deal combat damage.
