TemTem Showdown is a free to play battle game on steam. This game is identical to Pokemon, except you are battling players one on one in ranked battle modes.
You can battle your friends also in friendly battles which is nice. There are a lot of TemTems in this game and you are basically going to have to make a deck of 10 of your choosing and when battling it narrows down to 5 or 6.
Be warned the opponent you are battling can ban a few of your characters in your hand and you can also do the same, so be prepared. When battling, you can also basically pick who you want to attack and how you want them to attack, if you TemTem becomes weak you can always pull out another one using the refresh (switch button) and this will allow them to rest. If you TemTem is to weak you can always pass your turn by clicking the clock.
The kinds of creatures that are on here are Neutral, Wind, Earth, Water, Fire, Nature, Electric, Mental, Digital, Melee, Crystal and Toxic, there are a lot of categories and plenty to choose from. Each one has two traits that allow them to battle better. This can even protect them but be warned sometimes it will drain them and cause more harm so.
