Salrus, Knight of Damnation

First Strike, Vigilance, Deathtouch
Whenever an opponent sacrifices an artifact they control, you may create a number of treasure tokens equal to the artifact's converted mana cost.

When Salrus attacks an opponent, they may sacrifice an artifact they control with converted mana cost greater than or equal to Salrus's power to negate all combat damage that Salrus would deal this turn.
