mtg legal unfinity cards Made a completely illegal deck. Used all Unfinity with the exception of Mana Rocks lands and commander because I wanted to use all 5 colors. Anyone else out there build Magic: The Gathering Unfinity Collector

If you put this on a good non-legendary creature while an opponent controls their commander, you force them to sacrifice one to the legend rule

While Mox Amber does require you to have a legendary creature or planeswalker in play to add mana, given the nature of Commander and the huge number of legendary creatures and planeswalkers Magic has been printing lately, it is very easy to activate

For instance, if you get a quest asking you to win two games with a red and blue deck, include a copy of Countervailing Winds in your deck and now your deck it is considered a red-blue one

Each player has their own deck of cards, purchased and constructed from a limited pool of available cards
