Welcome to WeMod. 
A Steam trainer for Tyranny already exists: Tyranny Cheats and Trainer for Steam
If you want the trainer to be updated or want a trainer for the Origin or GOG version of the game, you need to vote for a trainer to be made, so that the trainer makers are aware that enough people want it: https://www.wemod.com/cheats/tyranny-trainers.
Or, if you meant Tyranny Gold Edition, you can vote for that here: https://www.wemod.com/cheats/tyranny-gold-edition-trainers.
