When Supercell were mentioning about hero cards, I thought of a new idea. Why not hero upgrades? This will basically be an upgrade that makes a card even better, and will require a huge amount of gold. This, for some will hate as it will make it more p2w, but I can stop that. To make it available to upgrade, they will need to play a certain amount of matches with that card. The upgrades should follow the star levels or maybe before them.
I haven't thought of a design for each card, but I will give an example for elixir collector.
The elixir collector will be changed to a elixir storage tank. It, during its lifetime, can store 2 extra elixir. This means that if 1 was in use, then a total of 12 elixir could be stored. When the pump dies, if there were elixir inside it then it would go to waste.
That's all for this time, thanks for reading!!!
