Darth Malak

Whenever Darth Malak or another Sith enters
the battlefield under your control, gain control of
target creature until end of turn. Untap that
creature. Until end of turn, it gains haste and
becomes a Sith in addition to its other types.
"There's nobody left who remembers who I was
before. But they'll remember Malak. I'll make sure
of that."
