Soul Link

As a warlock you should really consider having a Soul Link in your deck. This Demonology Hero Only (Radak Doombringer and Zenith Shadowforce) ability allows you to place a damage onto an ally in your party to prevent 1 damage to your hero this turn.

This can be used defensively (obviously) but also on offense. If you attack with Ya'mon then buff his attack by putting a couple of damage on him (Ya'mon has +1 Atk for each damage on him). You can buff Blood Guard Mal'wani in the same way. CArds like Arnold Flem and Vexra Darkfall can be damaged to activate thier destruction effects. If only Life tap damage could be prevented...

Overall this 4 cost ability is a pretty good card to pack in a warlock deck.
