The most typical representatives of latent negative effects are "Lying Ginseng" and the "Robbery Path Loss" in front of them.
They are both Giant Cards, occupying two spaces, but have no bonus to health points.
In other words, revealing them would directly result in a loss of 100 health points from the card deck.
It's the same with "Giant Zombie", occupying three spaces with only 200 health points, a pure loss of 100.
Among the Giant Cards that Ree has seen, the top one is "Giant Iceworm", occupying two spaces and only losing 50 health points, and the score is high, reaching 90 points.
However, the compatibility of this card is very low, till now, there hasn't been a single one that can fuse. All are explosive cards.
Also, concentrating too much score on a certain card will result in too low scores for other cards. Once the high scorecard is turned over by others, then it's game over.
The most typical representative of explicit negative effects is the "Tree Giant" card.
