Upgraded

• Cost: 1
• Effect: Gain 10 Block. Add a Soul+ to your draw pile.

A standout 1-cost Skill with premium Block (8-10) and Soul production together. Defense plus Soul generation in one card makes it the rock-solid defensive backbone of any Soul-focused deck.

Upgraded to 10 Block and Soul+ (the enhanced version of Soul), the cost efficiency is absurd. If the deck runs Possession or Soul Eater, Gravekeep becomes the default every-turn play — Block goes up, and the Soul you added drops into circulation.

Rating: A-tier (Block + Soul generation, the defensive cornerstone of Soul decks)

• Use as a default every-turn play in Soul decks for simultaneous defense and resource
• Upgrade is high priority because Soul+ is much stronger than regular Soul
• With Possession out, the Soul added lands in draw and deals damage once drawn next turn
• Combine with Soul Rip to pack the draw pile with Souls and amplify Soul Storm

• Possession: enemy loses 6-8 HP whenever a Soul is played. Gravekeep's continuous Soul supply is a reliable damage source
• Soul Eater: Summon 1-2 every Soul played. Gravekeep fuels it, growing Osti at the same time
• Soul Storm: damage scales on Exude Soul count. Gravekeep feeds the draw pile, Souls cycle through
• Soul Extraction: Adds 3-4 Souls at once. Combined with Gravekeep, Soul count climbs rapidly

• Early Act 1: top priority. Among the best commons — 8 Block is top-tier Necrobinder defense with Soul generation on top
• Late Act 1: top priority. Defense + Soul supply at every stage of the game
• Act 2+: high priority. Consider multiple copies as the defensive backbone of Soul decks
• Boss rewards: medium. Being a common it doesn't appear in boss rewards, but always grab it from card rewards
