Legacy Ninjas deck
UPDATED MARCH/2022
Ninjas is an interesting deck. The ninja strategy was once seen almost as a meme deck for years, but it eventually evolved into one of the most competitive Legacy strategies. It is an aggro/tempo strategy.
Overview
It takes advantage of Ninjas' most notable ability, which is Ninjutsu.
The idea is to use a creature with evasion (flying, unblockable, etc) to attack. The creature will become unblocked and the player will then be able to activate a Ninjutsu ability.
This lets the player take advantage of creatures with ETB (Enter-the-Battlefield) abilities like Baleful Strix.
The deck, as seen below in the example decklist, can be done without any Reserved List cards and perform well in a competitive environment. This makes it a very interesting choice for new players in the format who want to experience Legacy without paying for old duals.
