Learn to time skill use for when it's most advantageous in making wow gold. For example, use Death Grip and Chains of Ice to wrangle in a mage or warlock after they've used Blink or Demonic Circle. That way, they can't just teleport away. Death Grip is also great as an emergency interrupt. Learn what status effects each one cancels or avoids and be ready to use them to outlast and survive. For example, Lichborne will turn you undead, thus make you immune to most forms of traditional crowd control, and Anti-Magic Shell not only absorbs magic damage but poisons too, and it'll leave you immune to negative effects such as traps and roots as well.

Use your Ghoul's Gnaw to break up a stunlock by using it just as your enemy's stun is about to wear off, giving yourself time to get away from them or put up your own defenses before they can recover (and in the case of rogues, use another stun). Likewise, don't forget to use Icebound Fortitude, Lichborne and Anti-Magic Shell. Plus, the shell gives you plenty of runic power of wow gold, so when it's time to burst your target down, you have three Death Coils ready to go for wow gold.

This can give you emergency runes for a Chains of Ice or Strangulate or another such spell, or it can be used while burst to provide you with another couple Scourge Strikes if your first burst doesn't finish off your target. Keep this button handy for sure to make wow gold. Another important tool to remember for a PvP death knight is Empower Rune Weapon.
