What is Alliance in Magic: The Gathering?

Magic: The Gathering has a plethora of new mechanics coming to the game with its new set Streets of New Capenna, which has lore loaded with organized crime. 

There are five crime families in the set, and each has its own playstyle and a new mechanic to go with it. All five families are represented by a three-color combination identical to the shards from the Alara block.
