Catalyst, Defensive Conjurer

When Catalyst, Defensive Conjurer enters the battlefield, target creature gets -X/-X until end
of turn.
Dark Veil - At the beginning of your end step, if
you control no creatures with defender, create a
0/4 black Wall with defender, and "When this creature dies, target player mills four cards."
"Oh, that wasn't a hex. You're just not very good."
