Ree Shil had pondered over this round's 3+1 card deck quite a bit.
First and foremost, the thrilling card would be the "Ghostfire-Youth."
"Ghostfire-Youth"
Chasing the wind, 60 points, A
Attack 30, 100/100, 0/3
"Expensive Vehicle-Passive": Ghostfire-Youth's score is doubled
"Short Circuit System-Passive": Ghostfire-Youth exits the game in the current round when the card is revealed
"Shattered Traction-Passive": When Ghostfire-Youth exits the game, it allows one of your Determination Summoning cards to be instantly summoned without any cost
"Self Overload-Passive": When Ghostfire-Youth exits the game, it inflicts 'True Damage' equal to its own score on two card reveal targets, which cannot be "defended" against
In the first round of the game, it directly deals 30+60+60=150 points of damage.
This is indeed the epitome of an explosive start.
It can even pull your teammate's summoning cards, which is incredibly powerful.
