Seren's Armory

When Seren's Armory enters the battlefield
create a 1/1 colorless Enthralled creature token.
(It cannot attack or block.)
Enthralled creatures you control get +1/+0 and
can attack or block.
"Bound by unseen chains, their wills surrendered to a
dark master's bidding. In their hollowed gaze, the
shadows of lost souls linger, echoing the whispers of
their forgotten identities."
