This is an aggressive deck that is looking to buff its own creatures using cheap instants and sorceries to force through a bunch of damage incredibly fast. This is another deck where the full powered version doesn’t require many rares or mythics, however I would definitely look at upgrading the manabase as a priority since this deck can’t really afford to be playing tapped lands early on and so the red white rare dual lands are very valuable in terms of consistency. The above list is the budget version and check below for the fully powered version if you want to make upgrades.
