ネクロバインダー

• Type: Skill
• Cost: 1
• Effect: All players Summon 6. Exhaust.

A cost 1 Skill granting Summon 6 to all players then Exhausting (removing itself permanently from the deck). You gain +6 Osty HP, but opponents also gain the same benefit, so it is designed for co-op or versus modes. In solo play, it effectively reads "cost 1, Summon 6, Exhaust."

Since Exhaust cards leave the deck, the card can only be picked once, but it can serve as a one-time large Summon. Cost 1 for instant Summon 6 (comparable to Bodyguard) then Exhausting has high value as a disposable emergency Osty heal. It is not as strong as Revive (Summon 25), but Exhaust keeps long-term deck quality intact while rapidly restoring Osty HP. Perfect as a heal on turns where you sacrificed Osty.

Rating: 3/5 (one-shot Summon 6 that Exhausts; keeps deck quality while restoring Osty fast)

• Use it as an emergency heal right after sacrificing Osty with Bone Shards or Sacrifice
• It cannot be repeated, but the one-time instant Summon 6 does not clutter the deck
• On turns where Sic Em is placed, playing Bone Legion does not trigger Sic Em because Summons are not Osty attacks
• Play it immediately if Osty is nearly dead and it is in hand

• Bone Shards: Sacrifice Osty for AoE damage plus Block; hold Bone Legion for next turn's recovery
• Sacrifice: Sacrifice Osty for Block equal to 2x max HP; rebuild Osty via Bone Legion to Sacrifice again
• Revive: Summon 25 for a full heal; Bone Legion is the Summon 6 Exhaust option to complement Revive
• Bodyguard: Cost 0 Summon 5 to 7; Bodyguard preferred for no Energy, but the two complement each other
• Necromastery: Converts Osty HP loss to AoE damage; restore with Bone Legion to set up Necromastery again

• Necrobinder Necromastery Combo (A Tier)
