Merchant is the most unique play style to the Block chain game. Merchants appraise heroes and extensions by considering how they are popular and useful. Based on the valuation, merchants trade them.
Players can trade heroes and extensions in MCH. Image of trading Trading in MCH is free-mark.
Even the management supplies new heroes and extensions, players can decide the price of the exiting heroes and extensions.
-What is popular for Worriers-Samurai-?
-What extension is suitable for farmer to clear the difficult nodes?
Merchants figure out these needs and gather heroes and extensions beforehand, and sell them after they become popular. 
Merchants trade NFT( Heroes, extensions, and land sector)
As we explain in farmer part, we can get original extensions by hitting nodes. We can purchase new heroes on shop from management.
Every month, management release new heroes on the shop. Merchants can generate profit by purchasing hero on the shop and by selling the hero on the market.
Merchants also can generate profit from existing hero by purchasing unpopular hero and by selling it after it become popular. In order to appraise heroes and extensions, merchants must know the needs of Worriers-Samurai- and farmers.
So, we highly recommend that you play not only merchants but also Worriers-Samurai- and farmers.
