I used it in 2 matches to see how it worked once before a 9 hit (feinting strike) once before a 8 hit (strong bludgeon) the dam was 8 and 9 what don't I understand its hard to waste a 4 in my deck that isn't doing anything especialy since it should be a jewel not a dog
You're intended to use its passive effect as a boost card, not use it actively. Basically, use a powerful attack first and All out Attack will automatically trigger and double that card's damage.
