Green Ceresmon

FIrst thing first, we would never forget the massive impact that Hidden Potential contributes to green meta, which "0" cost to play you can suspend 1 of your digimon to reduce the memory cost of the digivolution by 5. Imagine if green can evolve from LV3 to LV6 with zero cost by using LV4 and LV5 digimon with "download" effect and Hidden Potential to evolve to a LV6 digimon, that would be a night-mare for green opponent (which I actually experienced it in tourney).

The [BT2-047] Argomon, its inheritable effect that you can play 1 LV3 green digimon at rest without paying its cost when this digimon attacking. This effect gives green free LV3 digimon in the battle to use for download effect in the next turn or to rest when you want to use Hidden Potential. Basically, all the time green players almost pay nothing in their turn. The Ceresmon then can even rest opponent's digimon to trigger the "download" effect for other green digimon that has "download" when they is evolved into. (So if you play against Ceresmon green deck, don't let your digimon unsuspend)
