Idea: enchants
For 50 gems you can get a random enchant to help you for the next 5 hours.
Example: you roll for an enchant and get strength III now you get 15% more damage for every match you play for the next 5 hours, and you will lose time from the enchant while offline.
Health: gives you more health depending on enchant level (great for low health characters)
Speed: gives more speed depending on the enchant level (great for tanks)
Strength: gives more damage depending on the enchant level (great for all characters)
All three enchants can be stacked.
If you have an enchant (Ex: HP III) and get another (Ex: HP) enchant, the timer for you're previous enchant will be reset to 5 hours.
