In a burn shell you want goblin guide, price of progress, snapcaster, and you specifically DON'T want stifle and wasteland because your main wincon is price of progress. This list also doesn't want daze because daze's main strength is its synergy with mana denial. Between 4 force, 2 spell pierce, and sometimes 2 spell snare I never really miss daze in these kind of lists. Daze is also bad here because you want to have lots of mana open for snapcaster mage.
The tempo shell is the "better" deck because it has good matchups against most of the meta. The issue here is that the only advantage that UR tempo has over RUG or BUG or 4 color delver is that it's cheaper to build. However, if your meta has a lot of BUG (especially shardless BUG), the burn list will absolutely stomp at local tourneys. I think in that regard, UR delver with price of progress is the only list worth running since there's no deck that does quite the same thing, so it actually fits a niche in the meta. Although you're trying to build RUG and you can't afford it yet, UR tempo is worth building since it plays the same.
