Do not interrupt the Blood death knight. Bait Anti-Magic Shell with a cheap spell, then stun. Save your kick for their healer, and stay out of Mind Freeze while they Death Strike.

Death Grip into the Blitz clump plus Anti-Magic Zone on the node is the trap. Death Strike heals off the damage you deal. Vampiric Blood is their wall, not a kill.

Stop the dump during Vampiric Blood — Death Strike will top them. Drag casters out of Anti-Magic Zone. Sit Icebound Fortitude. Melee stop during Dancing Rune Weapon.

Death Grip pulls you off the node into Gorefiend's Grasp. Trinket Asphyxiate if you must leave the clump. Chains of Ice plants you for the trade — dispel the snare if you have it.

Go outside Anti-Magic Zone after Vampiric Blood and Icebound Fortitude are spent and Bone Shield looks thin. Shuffle sample is thin — they trade on Blitz, they do not burst.

Dumping a full go into Vampiric Blood or Anti-Magic Zone, or waiting for a Frost-style burst that this spec does not have.
