Beatdown
Beatdown is a standard type of Shadow strategy which aims to win skirmishes through sheer bulk and slaughter its way through the Fellowship until the Ring-bearer has no protectors left. The idea is simple: play minions with high strength, often supplemented with Fierce or Damage effects, put companions in the ground, wash, rinse, repeat until the Ring-bearer has to deal with the same powerful minions all on their own. Victory may come through wounding companions to death, or it may come through overwhelming them instead; the important thing is that they die in skirmishes. Frequently.
Shadow cultures that often use beatdown strategies include Isengard, Wraith, Sauron, Orc, and Uruk-hai.
Other Shadow strategies include archery, corruption, direct wounding, and swarm.
