Should consider to have some
Advance Scout in the deck. Why? You need to spot an
minion to be able to play most of the conditions. Also, if you draw cards with
tDLS and get your hand on your key card (
Mordor Fiend), you're able to discard
Advance Scout from play so you can use Fiend's text (he needs to be the only minion in play to use his text).
As much as this deck can be a real killer, if Fiend is at the bottom of your deck it's gonna be hard to win with a massive swarm. But with
Advance Scout I think we might improve furthermore the chance of success.
