Blue Steel

Blue Steel (蒼き鋼 Aokihagane) is a series of cards associated with the Gold Paladin clan.

Background
Blue Steel is the branch of Gold Paladin that serves as the navy of United Sanctuary in the alternate Cray of Cray i. All military roles in the Sanctuary are split between Gold Paladin and Guardian Force; Guardian Force handles homeland defense and intelligence operations, while Gold Paladin covers out-of-country military operations in land, air, and sea. Before the flood, Blue Steel was a relatively small troop; while not as small as the near-nonexistent Ayanami, the Sanctuary did not feel the need to raise a strong navy, as few threats ever came by sea. As a result, the core personnel of Blue Steel make up a relatively tight-knit group, composed of a band of comrades who know each other well.

After the flood, many Gold Paladin soldiers were moved to Blue Steel as the United Sanctuary scrambled to assemble a fighting force to combat Deep Thought, and Blue Steel swelled in numbers.

Playstyle
Blue Steel is the multi-attack-focused sub-clan of Gold Paladin. Many of its cards have abilities that allow you to accumulate four or more attacks in one turn, primarily by sending units back to the deck and then calling cards from the top of the deck. In this way, Blue Steel can accumulate an obscene number of multi-attacks as it chains attacking units from the top of the deck. A good comparison would be Spike Brothers; while Blue Steel doesn't hit as hard and the quality of their calls isn't quite as good, Blue Steel has better card advantage and hits much more often.

Blue Steel's unique mechanic, Chain, counts the number of cards placed on your circles by an effect this turn, in the same way the other navy, Aqua Force, counts the number of attacks you've done this turn. If you manage to chain a high number of calls in one turn, which Blue Steel is more than capable of, your units' powerful Chain abilities are unlocked.
