When Bryant, Skilled Engineer enters the battlefield, Sabotage — {4}
(Any player may pay the Sabotage cost except the

counters to target artifact. When the last time counter
is removed, destroy that artifact, and deal damage to
its controller and all other creatures they control
equal to the destroyed artifact's converted mana cost.)
