Seal gauge

Seal Gauge (ゲージ Fūsō Gēji) is a type of  exclusive to the  sub-clan of the  clan.

Like and s, seal gauges are placed face down in the gauge zone, associated with one of your units. When a unit leaves the field, all of its seal gauges are put into the drop zone.

However, there is one important difference: whenever your opponent's unit is retired by your card's effect, you put a seal gauge from one of your units into the drop zone. Cards that give themselves seal gauges generally gain bonuses whenever they have no seal gauges equipped to them. Even if you have multiple units with seal gauges, you can only remove one seal gauge at a time.
