Ice Age block
The Homelands () expansion, released after Ice Age and before Alliances, was originally considered to be a member of the Ice Age block, although it included none of the mechanics or themes of the block.
The Ice-Age block is the only block in Magic's history in which one expansion (Homelands) has been removed and replaced by a newer one (Coldsnap). This also means that Coldsnap is the only Modern legal set from this block.
Theme decks[edit | edit source]
Theme decks were not introduced until the Tempest block. But, because of the later addition of Coldsnap to this block, this block now has theme decks.
