ネクロバインダー

• Type: Attack
• Cost: 0
• Effect: Osty deals 4 damage. Whenever you play a card that costs 2 or more, return this from the discard pile to your hand.

A special cost 0 attack where Osty deals 4 damage that auto-returns to your hand from discard whenever you play a cost 2+ card. Since it bounces back each time a high-cost card is played, it effectively becomes "use as much as you want per turn."

Decks leaning on high-cost cards like Deathbringer (cost 2), Reap (cost 3), Taunt (cost 2), or Revive (cost 3) keep cycling Right-Hand Man back to hand, stacking endless Osty attack counts. The synergy with Rattle (damage multiplier based on Osty attack count) is especially strong, as chaining high-cost cards pumps Rattle's damage to massive levels.

Rating: 4/5 (powerful cost 0 attack that stacks infinite Osty attacks in high-cost decks)

• Shines on turns with heavy use of cost 2+ cards like Deathbringer, Reap, or Taunt
• Combine with Rattle so Right-Hand Man returns each high-cost play, then finish with Rattle for huge damage
• Pair with Flatten (cost 0 if Osty attacked) to build a cost 0 attack chain
• With Bone Up, 4 damage becomes 8, and each recurrence adds up fast

• Rattle: Damage scales with Osty attack count; Right-Hand Man returning on every high-cost play piles up attacks
• Deathbringer: Cost 2 high-cost card; playing it returns Right-Hand Man every time
• Bone Up: +4 on Osty attacks; each recurrence compounds total damage
• Sic Em: Summon 2 to 3 per Osty attack; extra attack counts from Right-Hand Man mean more Osty healing
