After an intense competition of the best Magic: The Gathering Arena players, Shinya Saito won the Arena Championship 4 with a Blue/Red Wizards deck.
Although the 5th anniversary of Magic: The Gathering Arena has been mired with technical issues, the competition was still fierce during the Arena Championship 4. Wizards of the Coast held the two-day virtual event, which saw 32 players vie for the title as well as the prize pool of $200,000.
By the end of the fierce weekend eliminations and the final 8 clash, Japan's Shinya Saito won with his Izzet Wizards deck over USA's Bassel Nasri and his Dimir Control deck.
Since the release of Ravnica with its two-color themed guilds, fans have referred to color combinations based on them. This helps to easily identify the meta-game and theme of the decks played, especially among Magic: The Gathering players. For instance, instead of saying a player used a Blue/White control deck, it would be referred to as an Azorius Control deck (Azorius being the Ravnican guild with that color combination).
In the case of Shinya Saito's winning Historic constructed deck used in Arena Championship 4, it is an Izzet Wizards deck. The color-combination is Blue and Red with Wizards being the prominent creature type. It relies on efficient library management and card draw, while its creatures gain or give significant advantages the more instants and sorceries are cast during play.
