Considering the likes of Jinzo and Dark Armed Dragon are Dark attribute, this could only end in disaster if it ever became a real card.
One thing the Sword & Shield era failed at was its many gimmicks that the TCG always does to mix up every era.This era tried too many and only a few were actually good enough to stick around
This card was the linchpin of many combo strategies, but it was eventually banned in Legacy and restricted in Magic's Vintage format
Like most Pokmon cards, the value of Karrablast depends on a few consistent factors: its rarity, the printing and finish (regular or foil), its physical condition, and the set it was printed in (Brilliant Stars)
So as far as strategy goes I would recommend using a spread damage type Pokemon like the Spiritomb card from this set paired with Giratina so almost every Pokemon you see would have damage on it
Coalossal isn't a fan favorite, so the card art does a lot of work in making this card desirable
