## What is the Merge process?
Here we are at the **final step** of the crafting process: **merge**. In the complete process of evolving CTA cards, it's important to have previously gone through the steps of power up and awakening:
1\. [Power Up](https://whitepaper.crosstheages.com/guide/en/tcg/crafting/01-power-up)
2\. [Awakening](https://whitepaper.crosstheages.com/guide/en/tcg/crafting/02-awakening)
**3. Merge**
**Merge** is the stage that maximizes the power of CTA cards, creating a new category of cards, **combo cards**. Not all cards can become combo cards. To find out which ones can, please go to the articles of the corresponding collections: [Season 01 - Arkhante](https://whitepaper.crosstheages.com/whitepaper/en/products/tcg/collections/s01-arkhante/arkhante-collection), [Season 02 - Mantris](https://whitepaper.crosstheages.com/whitepaper/en/products/tcg/collections/s02-mantris/mantris-collection)...for instance.
## How to Merge Cards?
As the title means, to create a combo card, you need at least **2 alternative cards** and Trisel, just like at every crafting stage. The amount of Trisel required still depends on the rarity of the cards. **It equals of the quantity of Trisel necessary to** [**awaken**](https://whitepaper.crosstheages.com/guide/en/tcg/crafting/02-awakening) **a card**:
There are also multiple combo cards, requiring more than 2 cards. The merging process remains the same.
## Key Points
### **Grades**
The combo card created will have at least a +25 power level from the most powerful of the two sacrificed alternative cards. You can combine different grades (i.e C with A). But be aware that it is the lowest grade that is taken into account for the probabilities. You understand, merging a grade C with a stronger one is not so wise, but it's possible!
### **Rarity and Arkhome**
Two sacrificed alternative cards of the same rarity and Arkhome will result in a combo card with the same rarity and Arkhome. But you may have noticed that it's possible to merge two alternative cards of different rarity and/or Arkhome. In this case, the created combo card will take on the higher rarity, and the Arkhome will have a 50/50 probability, as in the following example:

## FAQ
**1. When I merge two alternative cards, do I keep them and receive a new card, a combo card?**
During the merge, the two merged alternative cards are sacrificed, meaning they are destroyed. In the game's jargon, we say they're "*burned*."
**2. Can I merge standard cards?**
No, merge is only possible with alternative cards.
**3. Can I merge any alternative card?**
No, a list of combo cards is predefined in each collection. To find out which combos are possible, refer to the specific collection: [Arkhante](https://whitepaper.crosstheages.com/whitepaper/en/products/tcg/collections/s01-arkhante/arkhante-collection), [Mantris](https://whitepaper.crosstheages.com/whitepaper/en/products/tcg/collections/s02-mantris/mantris-collection), and others.
