I have a couple suggestions for Steemmonsters.
Temporary boosts: There could be a few ways to go about this. One could be a level increase for one battle. Some battles are more important than others. If it is the last battle needed to level up or finish daily quest and you really do not want to lose it, you could use the boost to increase your odds. The boosts could either be awarded randomly through quests, sold in the store, or both,
Allow cards to be rented, it would be nice if we could rent out our cards. This would be a benefit to both new players and also players that have extra cards not being used. obviously this could be abused so there would need to be some safeguards in place.
I've been playing for about a month now and am really enjoying the game. I have invested some into this and hopefully will turn profit over next few months. Fingers crossed.
