Magic: The Gathering's Dominaria set is a remastered version of the original Dominaria block, which was released in 1997 and 1998. The set brings back many fan-favourite cards and mechanics from the original block, as well as introducing some new ones.

One of the most exciting aspects of the Dominaria set is the return of legendary creatures. These powerful creatures have unique abilities and can be a key part of any deck. Some of the legendary creatures in the set include Multani, Yavimaya's Avatar; Teferi, Hero of Dominaria; and Jodah, Archmage Eternal.

The set also introduces a new type of card called Sagas. Sagas are enchantments that tell a story over the course of several turns. As you play through the Saga, you'll unlock powerful abilities and bonuses. The set has a total of 10 Sagas, each one featuring a different character or event from Dominaria's history.

Another new mechanic in the set is historic. Historic cards are artefacts, sagas, and legendary cards. These cards have special abilities that are activated by playing other historic cards. This encourages players to build decks that are focused around historic cards and allows for some interesting combo plays.

One of the most highly anticipated cards in the Dominaria set is the planeswalker Gideon, Champion of Justice. Gideon is a powerful addition to any white-based deck and has the ability to create a 4/4 Knight creature token, protect himself and your other creatures, or even transform into a 10/10 creature.

Overall, the Dominaria set is a great addition to the Magic: The Gathering TCG. It brings back some classic cards and mechanics, while also introducing some new and exciting ones. Whether you're a seasoned player or new to the game, this set has something for everyone.
