Cards like Corpse Augur with:

When Corpse Augur dies, you draw X cards and you lose X life, where X is the number of creature cards in target player’s graveyard.

or cards like Champion of Dusk:

When Champion of Dusk enters the battlefield, you draw X cards and you lose X life, where X is the number of Vampires you control.

are a bit problematic because the X should only be calculated once when the Trigger/Ability starts resolving.
meaning Draw Replacement Effects shouldn't affect the value X later on.

maybe we could use LastState might not work for the Die Trigger? @Northmoc @tool4ever can you test that?

a change might be problematic for AI to understand that.

I'm still waiting for the confirmation from Jess. https://twitter.com/Hanmac10/status/1522124991277551618
