Careful Study

Draw two cards, then discard two cards.
"The spirit that I have seen
May be the devil: and the devil hath power
To assume a pleasing shape; yea, and perhaps
Out of my weakness and my melancholy,
As he is very potent with such spirits,
Abuses me to damn me: I'll have grounds
More relative than this."
—Prince Hamlet. Act II, Scene II
