Tribute 1 "Ninja" monster to target 1 monster your opponent controls; banish that target. While that card is banished, its Monster Card Zone cannot be used. When this face-up card leaves the field: Return the card banished by this effect to the same Monster Card Zone, in the same battle position.
This card needs to be at least Semi-Limited. Seriously, most people don't run anti-backrow to negate this card. As there's only three monster zones, this thing is too OP to be unlimited. It's almost as bad as Yata-lockdown was back in the day in the TCG. Actually, this card makes me wish that we had Link Summoning in Duel Links. That way we could at least get an Extra Deck monster out and not be locked out.
