Void is a new element they introduced in set 19 for the paths of pain. If a ninja has the void element, its handcost can be payed by any element.
Set 21 reintroduced the anbu theme and more sharingan support( susano'o, kirin, madara). Also another deck type would be discarding the cards from your opponents deck.
Also when around gencon there will be a block rotation set 19 and up
The tournament packs were originally reprint cards with chibi art, but tournament pack 3 is all new ninjas. Their set number is between the normal sets.
