Upgraded

• Cost: 1
• Effect: Ethereal. Each turn, your first Attack deals 75% additional damage.

A Power with Ethereal. Though it vanishes at end of turn, once played it delivers a lasting buff: every turn's first Attack gets a damage bonus. Upgraded 75% additional is a massive multiplier.

The 50-75% boost to the turn's first Attack turns cards like Reap (Retain 27-33 per turn) and Entomb (52-63) into devastating nukes. Synergizes with Ethereal-support cards too — play it the turn you draw it and lift every subsequent turn's damage.

Rating: A-tier (Power that creates overwhelming damage multipliers with big Attacks)

• The effect kicks in the turn it's played — use it the moment you draw it
• Make Reap, Entomb, or Blasphemy your first Attack to cash in the bonus
• Upgraded 75%: Reap 27 × 1.75 = 47, Entomb 63 × 1.75 = 110 — monster numbers
• With Paper Storm out, drawing Bloodlust itself triggers a bonus draw

• Reap: turn-after-turn Retain 27-33 balloons to 47-58
• Entomb: single-shot 52-63 balloons to 91-110. Needs energy but the ceiling is insane
• Blasphemy: Ethereal 13-17 balloons to 23-30
• Paper Storm: draw triggers on drawing Bloodlust. Land the setup without losing hand size
• Banshee's Cry: cost-capped 6 AoE 33 damage balloons to 58. Ethereal cost-reduction synergy makes it even stronger

• Necrobinder Ethereal Build (A-tier)
