空白之書

Empty Tome is a 0-mana Mana card that generates +1 Mana. Generating mana at zero cost makes it the foundational combo-starter of the game — it opens a chain while simultaneously giving you the mana to continue it. Every deck should include at least two copies; most include more.

• Effect: Mana +1
• Mana Cost: 0
• Color: Purple (Mana)

Empty Tome has no direct evolution path but qualifies as a Tome card for Magic Wand's evolution into Holy Wand.

• Chain Link arcana: Each 0-cost card played starts or extends a combo chain. Empty Tome is the most natural and risk-free opener.
• Mana Syphon: Permanently increases max mana based on cards played per run. More 0-cost plays means faster Mana Syphon stacking.
• Free to Play gem: Attaching this gem to Empty Tome lets you play it without spending mana while still counting as a 0-cost card for combo math — a pure combo extension with no downside.

Universal — every Crawler benefits. Especially essential for Arca and any build prioritizing mana economy. Minimum two copies are recommended in all builds.
