Dragonspark Reactor⁣ - Kamigawa: Neon Dynasty⁣ (Uncommon)⁣ [137]

Dragonspark Reactor is an artifact that costs {1}{R} to cast and starts building up charge counters whenever it enters the battlefield or when another artifact you control comes into play. For {4}, you can sacrifice it to deal damage equal to the number of charge counters to a target player and also deal the same amount of damage to one target creature. This card is particularly useful in decks that generate a lot of artifacts, as it can quickly accumulate charge counters and turn into a reliable source of damage. However, it does require a bit of investment to activate its ability, and if your opponent can remove it before you can use it, you might end up losing out on potential damage.
