This is my personal Izzet combo deck I made for really cheap.
The combo, for those who don't know, is any 0 mana artifact (Herbal Poultice, Darksteel Relic, Tormod's Crypt), any untapper (Zephyr Scribe, Nettle Drone), a bouncer (Retraction Helix, Banishing Knack), and a damage output (Reckless Fireweaver, Grapeshot).
I'll give three examples of an infinite damage combo.
1) Zephyr Scribe, Reckless Fireweaver, and Darksteel Relic are on board. You play Retraction Helix on Zephyr Scribe, tapping it to return Darksteel Relic to your hand. You then play Darksteel Relic from your hand, causing Reckless Fireweaver to do 1 damage, and Zephyr Scribe to untap. You then repeat the process, dealing as much damage as you please.
2) Nettle Drone and Herbal Poultice are on board. You then play Banishing Knack on Nettle Drone, tapping it to return Herbal Poultice to your hand. You then play Herbal Poultice from your hand, causing Nettle Drone to untap. You then repeat this as many times as you want, then cast Grapeshot, creating as many copies as you have bounced the artifact to your hand. Boom, infinite damage.
3) Say you flooded with the untappers, and got no Grapeshots or Reckless Fireweavers. If you have Nettle Drone and a second untapper, such as Zephyr Scribe, you can do the same combo as stated above, tapping Nettle Drone for damage, and tapping Zephyr Scribe for the bounce effect. Play Retraction Helix on Zephyr Scribe, then play Darksteel Relic, untap both Zephyr Scribe and Nettle Drone, tap Nettle Drone for damage, then tap Zephyr Scribe to bring back the Darksteel Relic, then repeat.
Banishing Knack and Retraction Helix are interchangeable in the combo.
Nettle Drone and Zephyr Scribe can both be targets for the bouncers above.
Darksteel Relic, Herbal Poultice, and Tormod's Crypt are interchangeable in the combo.
Grapeshot and Reckless Fireweaver are both interchangeable in the combo, and as stated above, Nettle Drone can also take these two's place if there is a second untapper.
If you have any suggestions, feel free to leave them.
