The previous card set was no longer suited for that newly recruited batch of card artisans to use. Their average perceptual strength was above level five. That was a lot higher than those previously under Chen Mu; their average perceptual level was at a standard of level four. If he was going to use a card set, the card artisans he had now could use a much more powerful one of a higher level.
The reason he had chosen the tactic of using a set of cards was to remedy the issue of the card artisans' insufficient level, which led to inadequate lethality. The shuttle cards had brought a tremendous lethality into play in the midst of the battle with the Downstream Alliance. However, thinking about it after things calmed down, there was a direct relationship between the somewhat low average level of the Downstream Alliance card artisans and the excellent performance of the tactical shuttle cards.
