How to Upgrade Cards

There are a total of 219 cards in Monster Train and they can be collected and upgraded in the course of a run in order to defeat the enemies you encounter. There are four different rarities of cards; Common, Uncommon, Rare, and Champion. Check out our How to Upgrade Cards guide to find out what upgrades can be applied to these cards to give them certain effects or increased stats.

On each turn in Monster Train you play cards to deploy minions on three levels of the train, and in each battle enemies enter at the bottom and move their way upwards towards the fourth floor, where your Pyre sits. The Pyre represents your HP and if it is destroyed by the advancing monsters, you lose.

On each run of Monster Train you choose a primary and a secondary clan. The starter clans, the Hellhorned and Awoken, are basically Red and Green, demons mixed with direct damage fireball spells, and sentient plants that can amass big pools of health. During your run you will have opportunities to improve your cards by combining and matching upgrades to open up new roads to victory. You can even duplicate your favourite card at special map nodes before facing off against the final boss. Below is a list of all the upgrades that are available in Monster Train.
