First of all, the game is good. Thank you for the updates so far.One suggestion, can we have some ways to utilise the common materials? I have more than 10,000 of each, and they can be so easily obtained, making them basically useless. Either change some of the common material drop to gold drop, or let us sell the common material for gold, even at a really cheap rate would still be better than stocking up a ridiculous amount.I understand buying materials would significantly change how you want to market the game, but just allowing selling materials would be good.Thank you.

If u dont purchase the stone, u never and ever get a good card in those free boxes. The drop rate are too low for those players who cant afford a huge amount to play games. Therefore if u are rich, u can play this game because the stones are very very expensive!!!

It takes 4 days to get a chance to play the Challenge in order to get 3 leaf thing to upgrade the tower cards. Even you spend 36 points of energy to play middle level and 48 point to play high level, you are not guaranteed to get those tools while you need at least 4 to upgrade one tower. So for upgrading one tower you need at least 16 days which is totally ridiculous.Too much money asked for upgrade And there are no mission to fight to money.

It gets boring after you’re stuck in a few levels, so adding new maps can let you get more materials to upgrade the cards. And more events please... don’t make me wait for an entire week without events...
