I can only get the lessons that are in the first seven slots, because, at the time, players put 14-15 different lessons without any downside in their sideboard, so WotC limited it to 7 slots in best-of-one to reduce this strategys effectiveness
With infect creatures, you only get one route to victory since they dont reduce life totals
Its the combination of all of these things that has Emiel the Blessed at the top of our list of the best flicker cards in MTG, but its a very well-contested list, so most of these cards could be up here
Or you could just play cards like Ashling, the Extinguisher or Draugr Necromancer or Elusive Tormentor and get a 4/4 black creature for four mana with all upside and no drawbacks
Both starter decks did what they set out to do in my first experience with them: introduce an easy entry point into the game while emphasizing the sets new Boost mechanic
