Ice Age

Ice Age as a term can refer to a few things:

• It can means a time when the world is covered in a constant winter, hence an Ice Age.
• It can means a series of mediocre movies by Dreamworks about a bunch of prehistoric creatures going on adventures.
• A two player board game where you control a bunch of humans trying to kill all the mastodons, not for food but for good old extinction. Fun fun fun.

Though most often /tg/ uses it to refer to the Magic: The Gathering block and first set in it, detailing the Ice Age caused by Urza after he unleashed the Golgothian Sylex to win the Brothers' War. At the end of the first set the Planeswalker Freyalise casted the World Spell to thraw Dominaria, which caused bad shit to happen so people had to form Alliances (the second set) to defend themselves. Finally, ten YEARS after the release of the set (and a retcon of the spectacularly shitty Homelands as the third set in the block) they released Coldsnap, which details what exactly happened during the end of the Ice Age.

Ice Age is known for adding a couple of new mechanics but the most famous one is that of Snow Lands: Lands who give both regular mana and snow mana, which was required for certain spells and abilities.
