Do not interrupt the Assassination rogue. Kick their healer — yours is silenced by Garrote. Envenom and Shiv are instants; do not spend the kick on those.

Garrote silence on your healer as Kidney Shot lands on you is the setup. Deathmark overlapping that stun is when Envenom kills. They Cloak of Shadows your first magic CC.

Stop casting into Cloak of Shadows — swap to physical or sit. Do not melee Evasion. Feint is AoE DR, not a wall. Vanish is a second opener — do not instantly AoE.

Do not trinket Cheap Shot — Kidney Shot is the kill stun. Blind is magic, dispel it. Garrote silence on your healer cannot be purged — peel the rogue off them.

Go when Cloak of Shadows is down and Kidney Shot is already spent. After Deathmark burns without a kill and Vanish is down, they are killable.

Trinketing Cheap Shot instead of holding it for Kidney Shot, or ignoring Garrote on your healer while you tunnel the rogue.
