Unfortunately for Modern players, this card just so happens to be a direct upgrade to the best deck in the format
Living Energy This deck, as the name suggests, has a focus on the Energy mechanic as well as artifacts and artifact payoffs
Others call it preservation
This effect is strongest as a Quick Effect, available only when you have another Subterror card face-up on the field, since you can chain the effect to your opponent's effects and use it on their turn
Some cards got a Japanese showcase treatment exclusive to DFT Collector Boosters, like Loot, the Pathfinder and Chandra, Spark Hunter
But there are also special tokens in there, such as the red doom token, or the skull tokens
