Unlimited Mana combo (under $2) (Modern)

Unlimited Mana Combo ($2)
2 Myr Galvanizer
1 Palladium Myr

1) Tap Palladium +2 Mana
2) -1 Mana Tap Galvanizer which untaps Palladium (Net +1 Mana)
3) Tap Palladium +2 Mana
4) -1 Mana Tap your Second Galvanizer which untaps Palladium and your 1st Galvanizer (Now + 2 Mana)
5) Repeat infinite times

If Palladium or Galvanizer gets killed you can use a Myr Welder to copy and ability from the graveyard. You can also use Twinflame to copy a Galvanizer if you only have one in play.

The main card in this deck is Twinflame which allows you to copy any creature card in the deck. This is important because many creatures have enter the battlefield mechanics that will trigger when the token enters the battlefield, such as draw cards or create tokens.

For example Myr Battlesphere can be copied to add an extra 4 1/1 Myr tokens. Since the copy has haste you can attack with it. The second ability will trigger in which you can tap all your Myr creatures (probably greater than 10 at this point) to deal direct damage to your opponent. You can then untap them all with Myr Galvanizer, who strengthens them. You'll probably deal lethal with attack damage. A similar theory is applied with Precursor Golem.

Since most of your deck is high cost Combustible Gearhulk can deal allot of damage or make you draw allot of cards. Since you can copy him you can draw over and over.

Twinflame can be used to copy your second galvanizer.

Win conditions are taking damage from opponent or winning with Hellkite Tyrant due to the shear number of artifact tokens made equaling 20 real fast.

For cheaper mana you could remove 4 Scalding Tarn and add 2 Island and Mountains. Similar can be said with Urza lands.
