So I started building an artifact deck
Red white black {R}{W}{B}
And noticed that {Blinkmoth Urn} is amazing for it. (After learning about mana burn I'm extremely happy it's not still a thing.) casting 2 {Urza's Armor} as well as playing a {Megatog} in one turn is quite the feeling :D (I use artifact lands though so I know it's not modern legal I simply use it as a just for fun deck)
