ネクロバインダー

• Type: Attack
• Cost: 0
• Effect: Osty deals 3 damage. If this is the first card played this turn, draw 1 card.

A cost 0 attack where Osty deals 3 damage and draws 1 card if it is the first card played that turn. The conditional draw tied to "first play of the turn" is its hallmark. Using it as the opening card every turn secures draw while stacking Osty attack counts.

Damage is low at 3, but cost 0 with draw satisfies both hand cycling and Osty attack count goals at once. Compared to Peck (cost 0 Osty 6 damage) the damage is weaker, but the draw bonus for leading with it is the differentiator.

Rating: 3/5 (cost 0 attack that draws and stacks attack count when played first)

• Play it as the first card every turn to lock in the draw bonus
• Stack Osty attack counts to enable Rattle, Flatten's cost 0 condition, or Sic Em's Summon trigger
• Cost 0 means you can add attacks without spending Energy
• With Bone Up, 3 damage becomes 7, a respectable number

• Rattle: Damage scales with Osty attack count; bank attacks with Fetch first then fire Rattle
• Sic Em: Summon 2 to 3 each Osty attack; Fetch's attack triggers Sic Em
• Bone Up: +4 to Osty attacks, turning Fetch into 3+4=7 damage
• Flatten: Cost 0 if Osty already attacked this turn; leading with Fetch enables Flatten at cost 0

• Necrobinder Osty Multi-Attack (S Tier)
