BUG control counter deck help please

Hello I made a bug deck using only the cards I have. I haven't really played much with it but only plan to use it casually, is there any must have changes I need to make, some cards that should never be played or what? im new to deckbuilding so please help. I already know shock and check lands are obvious.
