"Tachikaze" (たちかぜ) is a clan from the Dragon Empirenation. The clan is themed around dinosaurs and other prehistoric creatures and beings augmented with mechanical or artillery equipment. It is the elite ground assault troops of the dragon nation.
Tachikaze is based on the mechanic of Equip Gauges, named "Armed Equip Gauge" (武装 ゲージ Busō Gēji), reflects its theme of heavy weapons and artillery. Equip Gauges are stacked behind the player's rear-guards to then be used for a variety of purposes, common uses include gaining Power, generate resources, discard them as costs, activating stronger abilities if a rear-guard has a certain amount of gauges stacked beneath it, among others. Some abilities allow the moving of Equip Gauges between different rear-guards to better manage their usage.
Additionally, some of the units in the clan can retire other rear-guards as a cost to gain more Power and draw more cards, this works in tandem with rear-guards that trigger their effects when they are retired to recycle or replace themselves.
Tachikaze has the AccelImaginary Gift, which allows them to have more rear-guards to arm and attack with.
