I call this a watershed card because if this is the power level Wizards are aiming at for aggro, and people are still set on not playing sweepers, hatebears, or stax-lite, then yeah, this has quickly turned toward a turn 6-7 format
As with other lists like this, cards are very loosely arranged from least powerful to most, with the understanding that these rankings will shift from situation to situation and person to person
as well as non-combat reuse of comes-into-play creatures (Jilt your own Flametongue Kavu, perhaps?) Barrin's Spite was a rare in this block and served generally the same purpose as Jilt, except that Jilt was an instant, and Jilt allowed you to unsummon your own creature if need be
They can still tap these lands for colorless mana
You have a handful of removal spells to bring in that work well at a baseline and happen to answer stray sideboard permanents like Grafdiggers Cage
