ネクロバインダー

• Type: Attack
• Cost: 1
• Effect: Osty deals 7 damage. Repeat additionally for every time Osty has attacked this turn.

An explosive attack whose damage scales exponentially with Osty's attack count that turn. If Osty has attacked 3 times before Rattle, 7x(1+3)=28 damage; 5 times means 7x6=42 damage. Damage scales dramatically.

The basic Osty attack combo chains Peck (cost 0 Osty 6 damage), Fetch (cost 0 Osty 3 damage), and Right-Hand Man (cost 0 Osty 4 damage, recurs on high-cost plays) first, ending with Rattle. Bone Up (Osty attack +4) buffs each hit too.

Rating: 5/5 (ultimate finisher for Osty multi-attack decks; damage explodes with attack count)

• Play at the end of the turn for maximum attack count benefit
• Chain cost 0 Osty attacks like Peck, Fetch, and Right-Hand Man before firing
• Pair with Sic Em's Summon trigger to manage Osty's HP while stacking attacks
• With Bone Up, each repeat gains +4, so 5 repeats add +20 damage total

• Peck: Cost 0 Osty attack; ideal for racking up attack count before Rattle
• Right-Hand Man: Cost 0 Osty attack that returns on high-cost plays; infinite Osty attack stacking
• Bone Up: +4 per Osty hit; each Rattle repeat gains +4, huge total boost
• Sic Em: 2 to 3 Summons per Osty attack; pre-Rattle attacks also heal Osty
• Flatten: Cost 0 after Osty attacks for 12 to 16 damage; finish with Flatten after Rattle
