What's a good Android game for merging units to create a powerful army?

Top War: Battle Game offers a unique merging mechanic that sets it apart from other strategy games. Instead of simply training units, you merge identical ones to instantly level them up. This eliminates long training times and allows you to quickly build a formidable force. The game features a variety of unit types, including land, air, and naval forces, each with its own strengths and weaknesses. By strategically merging and deploying your units, you can create powerful combinations to overcome your enemies. Top War also includes base-building elements, where you construct and upgrade your base to unlock new technologies and resources, further enhancing your army's capabilities. All of this makes Top War a compelling option for players who enjoy strategic army building and resource management.
