The Limited decks of The Hobbit— learn each one's plan, signposts, and key cards.
Midrange deck about power 4+ creatures (Ferocious). Wolves and pump effects turn on payoffs that reward having a big creature on board.
Aggressive Goblin tribal deck using Amass to grow an Army while chipping in damage. Sacrifice and death-trigger payoffs convert expendable bodies into value.
Elf ramp-tempo deck using Landfall triggers. Extra land drops and land recursion snowball incremental advantages into oversized threats and card flow.
Dwarf tribal deck built around Storied: once you control three or more artifacts, legendaries, and/or Sagas, you have an 'enduring story' for the rest of the game, permanently upgrading your Storied cards.
Go-wide Humans deck built around the Recruit mechanic: assemble a board of Human tokens and creatures, then leverage payoffs that reward a large Human count.
