If not all Machinas in the team have 100% fuel, then it's basically a x4 Team Damage multiplier.

Otherwise, considering the Machinas already deal an extra 25% to 50% damage in extra attacks, activating this skill lets it go from x1.25~1.50 to x4.25~4.50. That's the equivalent of a x3.4~3 (x3.18 on average).

Disclaimer: that's before factoring any potential damage relation bonus or monster defence. Since all monsters have at least some defence, more attacks are less valuable than a straight damage buff, in terms of damage dealt.

Just from the damage buff alone, it's pretty good, but CD8. There's some enchanting for the next wave too, though.

On the upside, that's a massive number of attacks, for the few bosses that require you to deal a 30+ something attacks before receiving damage. It also bypasses the "only receives damage from X colour" shields (unless Light or Dark).

Probably one of the better cards from the Joint Operations... but being most suitable for all-Machina teams make it pretty niche.
