NAME: Demonic Altar ELEMENT: Darkness COST: 4 TYPE: Permanent ATK|HP: N/A TEXT: When opponent play a spell card, gain hp which matches the card cost. Absorb 1 Darkness quanta per turn.	NAME: Demonic Altar ELEMENT: Darkness COST: 6 TYPE: Permanent ATK|HP: N/A TEXT: When opponent play a spell or permanent card, gain hp which matches the card cost. Absorb 2 Darkness Quanta per turn

ART: N/A IDEA: Shadow1128 NOTES: Permanent Affect can stack. Which means that if opponent play Miracle and you have 6 Demonic Altar, you will gain 15 x 6 = 90 Hp! Ya is 90 HP...but i think it need lucks so hope not op... Moreover, when using creature or permanent skill, Demonic Altar wont heal. Please give me some idea or suggestion which can help me improve my idea...thanks! SERIES: Nope
