Yuriko and Kozilek

Ninjutsu {u}{b} ({u}{b}, Retrurn an unblocked
attacker you control to hand: Put this card onto the battlefield from your hand tapped and attacking.)
When you cast Yuriko and Kozilek, if you have
fewer than 7 cards in hand, draw cards equal to
the difference. Yuriko and Kozilek enters the battlefield with that many +1/+1 counters on it.
Whenever a Ninja you control deals combat
damage to a player, draw a card.
