Strategy and Deck Building

Vaelastrasz is essentially playing a Mill deck. What this means is that he aims to fill your hand as quickly as possible, causing you to overdraw, all the while playing minions such as Clockwork Giant and Goblin Sapper that take advantage of your large hand size.

This fight is easily combated by playing an extremely low curve deck. On Normal mode, if your deck is sufficiently low curve, you will often find that the boss is burning more of his own cards than he is of yours. With such a low curve, however, you still need to ensure you have ways to dealing with his large minions, so strong removal or buff effects are a must.

On Heroic, not only is his Milling strategy more aggressive, he also gains a Mana Crystal each turn, making a straightforward fight for value ill advised. Instead it is usually better to play relentlessly aggressive decks and rely on his Hero Power you draw you enough fuel to allow you to keep up the race.
