Does Helm of the Host copy equipment?

It doesn’t copy whether that creature is tapped or untapped, whether it has any counters on it or Auras and Equipment attached to it, or any non-copy effects that have changed its power, toughness, types, color, and so on. The token isn’t legendary, and this exception is copiable.

Is Teysa Karlov dead?

Teysa remained in prison for a long time, because the Ghost Council was extorting corrupt officials to make sure they kept her locked away. At the same time, she was magically kept alive to prevent her from becoming a ghost.

What do you get with Teysa Karlov 2wb?

For 2WB you get a 2/4 Legendary Human Advisor that gives all your creature tokens vigilance and lifelink, which is fairly spicy already- but her first ability is the heavy hitter, here. “If a creature dying causes a triggered ability of a permanent you control to trigger, that ability triggers an additional time”.

What happens when Teysa Karlov leaves the battlefield?

For regular ‘leaves-the-battlefield’ triggers, the game can look back in time. Normal “when this thing dies” triggers and “Whenever a creature dies” triggers of your stuff will get doubled even if Teysa or the triggering permanent are going down. Let’s say you have four Blood Artist s and one Teysa Karlov, and your opponent decides that’s no bueno.

Can a creature be doubled by Teysa Karlov?

No, no, and sometimes! The exploit triggers are looking for a creature being sacrificed by the Exploit triggered ability, not just for something dying. Something does technically die, but the trigger condition for them is more specific, so it won’t get doubled from Teysa.

Can a turntimber Sower trigger on Teysa Karlov?

For those, it will work, but only if Teysa herself and the triggering permanent are still on the battlefield immediately after the death of the creature that caused the trigger. So let’s say we have a Turntimber Sower on board, and an animated land like Treetop Village.
