The Mandalorian

First Strike, Vigilance
Whenever The Mandalorian attacks target player sacrifices a creature with the greatest power
among creatures they control. If that player can't,
they put the top 4 cards of their library into their graveyard, lose 3 life, you gain 3 life, and you
create a number of treasure tokens equal to the
number of creatures that entered the graveyard
this way.
