Mana Vault ei toimi Power Artifactin kanssa kovin hyvin, koska sen voi tosiaan untapata vain kerran vuorossa.
Mana Vault: {1} |Artifact| Mana Vault doesn't untap during your untap step. / At the beginning of your upkeep, you may pay 4. If you do, untap Mana Vault. / At the beginning of your draw step, if Mana Vault is tapped, it deals 1
damage to you. / T: Add 3 to your mana pool. A,B,U,RV,4E,5E-R
Power Artifact: {UU} |Enchant Artifact| Enchanted artifact's activated abilities cost up to 2 less to play. If this would make an ability cost 0 or less mana to play, it costs 1, plus any nonmana costs. AQ-U3
