Blocks are cycled out of Standard tournament play after a while. Currently, the legal blocks for Standard tournaments are Iron Throne, Winter, and Valyrian. In Classic tournaments, you can use cards from any block, including Ice & Fire and Westeros.

Iron Throne Block (Iron Throne Edition) The battle for The Iron Throne can be fought on many fronts, and Crests allow new powers to press their claim. Will you let Randyll Tarly lead your War characters into the fray, or appeal to the Holy to extract a Confession from the heretics? (A House of Thorns) The Roses have held back long enough, and now Mace Tyrell and his followers are ready to pick a side. The Boltons come out of The Dreadfort and march to war, but is Roose Bolton on your side or your opponent's?

Winter Block (Winter Edition) Winter is here. Cards such as Field of Fire are more powerful than ever, but play too many and you may be doomed. The Others start making their presence felt, and those who are not careful will discover that Winter has Come. (A Song of Twilight) The Wildlings mass beyond the Wall and ready their assault. Will the Night's Watch be able to stop them? Get ready for the Last Battle at the Wall! (A Song of Night) Battles spread across the realm. Fight in famed locations such as the Mouth of the Blackwater and the Fields of Ghiscar. Many will perish - and those who do may find themselves Risen from the Cold. (Winter Premium Starter) Featuring House Greyjoy and House Targaryen. Reprints include the vital Westeros Bleeds and The Red Keep. New cards include the powerful plot Loyalty Money can Buy and the game-winning event The King Must be a Kraken

Valyrian Block (Valyrian Edition) See the heroes of Westeros before they became aged, maimed, or dead. Characters are viewed in the prime of their life, and woe to those who would oppose them. Valyrian Edition also introduces influence - a new resource that can be used to pay for powerful events such as Arya Stark and We Have the Princess. (A Tourney of Swords) Tourney season is upon us! Knights from all the great Houses ride to compete. Compete in Jousting challenges with characters like the Tourney Knight and the reward for victors may be sweet. Which House will play the spoiler. . . ? (A Reign of Kings) Four kings lay claim over Westeros, and one queen waits far to the east. Robb Stark, Joffrey Baratheon, Stannis Baratheon, Balon Greyjoy, and Daenerys Targaryen lead their factions with powerful abilities. But the small can still prevail. Specialized characters such as the Scholar of Poisons allow the weak to triumph. (Valyrian Premium Starter) Featuring a Stark/Baratheon Treaty and a Lannister/Martell Treaty. New cards include Acolyte of Asshai, while reprints include the powerful The Blackfish.

Ice & Fire Block (Ice & Fire Edition) (A Throne of Blades) (A Crown of Suns) (Ice & Fire Premium Starter)
