Still, $deck is an Array and you want to delete from $deck and not
from any of the Hashes in the Array!

Please rethink.

Array#delete

(from ruby core)
------------------------------------------------------------------------------
  ary.delete(obj)            -> obj or nil
  ary.delete(obj) { block }  -> obj or nil

------------------------------------------------------------------------------

Deletes items from self that are equal to obj. If any items are
found, returns obj.   If the item is not found, returns nil. If
the optional code block is given, returns the result of block if the
item is not found.  (To remove nil elements and get an informative
return value, use #compact!)

  a = [ "a", "b", "b", "b", "c" ]
  a.delete("b")                   #=> "b"
  a                               #=> ["a", "c"]
  a.delete("z")                   #=> nil
  a.delete("z") { "not found" }   #=> "not found"


Array#delete_at

(from ruby core)
------------------------------------------------------------------------------
  ary.delete_at(index)  -> obj or nil

------------------------------------------------------------------------------

Deletes the element at the specified index, returning that element, or
nil if the index is out of range. See also Array#slice!.

  a = %w( ant bat cat dog )
  a.delete_at(2)    #=> "cat"
  a                 #=> ["ant", "bat", "dog"]
  a.delete_at(99)   #=> nil

No idea as I don't know what your game is about and how it is supposed
to be played.

Kind regards
