Anje's Commander

When Anje's Commander enters the battlefield,
if you cast it for its madness cost, it gains trample
and haste until end of turn.
Relentless — Whenever Anje's Commander attacks,
you may sacrifice a creature. If you do, put a +1/+1 counter on all attacking vampires you control and
all cards in your hand gain madness until end of
turn. The madness cost is equal to its mana cost.
