レインボー防御力

Rainbow Armor is a 2-mana Defense card that grants +6 Defense. It provides the highest Defense value of the Armor card series in a single card, making it the most efficient defensive option at the cost-2 tier. With Shield Bash arcana, the +6 converts to 6 attack damage, making it simultaneously the strongest offensive card at cost 2 in that build type.

• Effect: Defense +6
• Mana Cost: 2
• Color: Blue (Defense)

No direct evolution path, but serves as evolution material for Runetracer's NO FUTURE evolution as an Armor-type card.

• Shield Bash arcana: Converts Defense +6 into 6 Attack damage — cost-2 efficiency matches or exceeds most dedicated attack cards in that slot.
• Cost-2 combo rung: Fits the standard mana staircase (0 → 1 → 2) and works in mixed attack-defense decks.
• Defense-cap builds: The highest single-card Defense value makes it essential for builds trying to reduce incoming damage to zero.

Best in Shield Bash arcana builds. Also core to any Crawler aiming for extreme damage mitigation through stacked Defense.

The top cost-2 defensive card and primary damage source in Shield Bash builds.

Defense-only value is situational, but Shield Bash builds elevate this to S Tier as a primary damage source.
