I strongly suggest that if you can, try and get the daily rewards because a little bit of extra gold and gems won't hurt! Also, if you have a spare bit of cash, consider buying gems and/or gold to unlock slots etc. My personal preference is to not use items but if you feel the need to, than go right ahead. But be warned! Items are a single use only and you will have to keep buying them so use them wisely! Good luck and Game On!
