Upgraded - Extreme Budget Rakano Slingers

This took me from G2-Master in an evening.

Icaria or Jekk, Hunted Fugitive can be used in the market in place of Rizahn.

Morningstars can be used in place of Deepforged Plate, but the substitution lowered my win rate by 15-20%.

First-Shot Rioter and an extra Valkyrie Enforcer can replace Stella. She's a nice bonus, but not super crucial to the deck--mostly just a body with Aegis. Realistically, you can sub in whatever gunslingers / weapons you'd like, as long as you keep the unit count at 30+ and don't put anything over 4-5 cost in your main deck.

Rakano Crests may also be helpful, but I haven't used them myself because I figure the power base is already dangerously depleted for an aggro deck.
