The 2-mana artifacts are at their absolute best in mono-colored decks, where their cost reduction applies to nearly all cards in the deck

Your commanders colors (the mana symbols on the card) determine what color cards you can put in your deck

The play pattern here is to get Vivi in play, pitch a huge red spell card to cast a free Blazing Shoal and make Vivi enormous, then use Vivi's ability to generate loads of free mana and cast more giant spells, storm off, or simply swing and deal heaps of damage to your opponent with the now embiggened mage

Xenagos on the other hand, costs 1 mana more, but needs 7 devotion to become a creature

Storm decks tend to use black mana a lot, so its especially good there
