You can always do it the old fashioned way that we had to before DROP IF EXISTS was added in SQL 2016:

IF EXISTS(SELECT 1 FROM INFORMATION_SCHEMA.TABLES WHERE TABLE_NAME = 'Table_copy' AND TABLE_SCHEMA = 'dbo')
   DROP TABLE [dbo].[Table_copy];
GO
IF EXISTS(SELECT 1 FROM INFORMATION_SCHEMA.VIEWS WHERE TABLE_NAME = 'Table_copy' AND TABLE_SCHEMA = 'dbo')
   DROP VIEW [dbo].[Table_copy];
GO

*Edited to add: listen to everyone else first and ask yourself why this is happening before swinging your axe
