Here is a first pass at how I would look to build it now with a deeper pool of high powered ninja on offer
Jin-Gitaxias, Core Augur is perhaps the most brutal of these cards, giving you seven extra cards at the end of every one of your turns while simultaneously reducing each opponents maximum hand size to zero, barring they themselves do not possess a card like Reliquary Tower or Spellbook
Ive highlighted the two I thought were most powerful
While Town Greeter is at best a piece of filler for graveyard-focused strategies, Stolen Uniform could end up singlehandedly giving Colossus Hammer decks a shot to compete in Pioneer
Dont forget that Sauron, the Dark Lord is a 7/6 body that you can throw around alongside the Army
Other times, desirable expensive cards like Dockside Extortionist need additional printings to bring down their price on the secondary market
