Games like Battle Alchemy

You apprentice and heir of the great magician-alchemist, but, unfortunately, after his death, all the burden of worries and protection of the castle with the surrounding lands fell on your shoulders. As it turned out, the neighboring lords, having learned about the death of your mentor, decided that now the surrounding lands were left without protection, and would not mind annexing them to their possessions. You have no choice, it's time to apply your skills, and put in place the hostile and greedy neighbors.
