ネクロバインダー

• Type: Skill
• Cost: 0
• Effect: Gain 7 Block. Add a copy of this card to your discard pile.

A 0-cost 7-Block Skill that adds a copy of itself to the discard pile on play. Because every use breeds another copy, the odds of seeing Undying again next turn go up, and as the deck cycles the number of Undying cards in hand compounds — a self-replicating Block engine.

Once it gets going, Undying effectively hands you repeated 0-cost 7-Block every turn. One copy in the discard after turn 1, two after the next cycle, and eventually multiple Undyings land in your hand every turn for free massive Block. The risk is that it can overrun your hand. Unlike Melancholy (3 → 0 cost, 13 Block), Undying is reliably 0-cost from the start — consistency is its appeal. It works against deck thinning, but delivers guaranteed free Block every turn — a true defensive cornerstone.

Rating: A-tier (self-replicating 0-cost 7 Block, ironclad sustain in long fights)

• Play it early and often to build up copies in the discard
• If the hand starts drowning in Undyings, play them without paying energy to keep the cycle healthy
• Best used as a filler — spend leftover energy on Block via Undying
• Undying decks conflict with thinning, so compensate with a 0-cost-heavy build

• Melancholy: 3 → eventually 0 cost, 13 Block. Stacks with Undying for multi-card 0-cost Block turns
• Friendship: +1 energy per turn. Block with Undying, spend the extra energy on aggressive cards
• Cloak of Shadow: high-Block Ethereal Skill. Combine with Undying to build a Block-focused deck
• Gravekeep: Power with extra triggers when Block is high. Undying piles up Block for the condition
• Soul Extraction: Skill that converts Souls to Block. Stacks nicely with Undying for massive Block totals
