Its fallen out of favor in most of the formats it once called home but in Standard as of Foundations , Lightning Helix, Boltwave, Boros Charm, and more are bringing the archetype a resurgence, with the help of another fan-favorite burn payoff
For example, if the second ability of Hoarding Dragon from the Foundations release ("When this creature enters, you may search your library for an artifact card, exile it, then shuffle.") is copied and two cards are exiled, then when Hoarding Dragon's third ability ("When this creature dies, you may put the exiled card into its owner's hand.") later resolves, if you choose to put "the exiled card" into its owner's hand, both exiled cards will be put into their owners' hands

The real question is, What effect does a density of Auras at common that dont come with the normal risk of card disadvantage have on a format? All I can do at this stage is speculate, but it mostly boils down to speed
