Myr are another combo tribe, which is good because Myr are mostly small and bad at attacking. The deck's main goal is to get two copies of Myr Galvanizer on the battlefield (with the help of Myr Turbine to find them) along with some mana-producing Myr. With two Myr Galvanizers, we can tap all of our creatures for mana, use one Myr Galvanizer to untap them, and then, after tapping all of our Myr for mana again, untap everything, including the first Myr Galvanizer with the second (untapped) Myr Galvanizer. This also allows us to make an infinite number of Myr Propagators and cast huge threats like Myr Battlesphere. Once we make about a million tiny Myr, we can finish our opponent off with one attack.
