Tag applied: Invalid Game ID
Testing applied: Tested War Room with different color identity Commanders.
Test Results: War Room's life cost for it's second ability was always equal to the Commander number of different colors in it's Color Identity.
The Game ID was analyzed and it does not contain War Room. To further the post we require a valid Game ID to investigate the potential issue.
Note: If the Commander has a different colored mana than it's mana cost in it's text for an activated ability, this colored mana also counts towards the sum of it's color identity.
903.4. The Commander variant uses color identity to determine what cards can be in a deck with a certain commander. The color identity of a card is the color or colors of any mana symbols in that card’s mana cost or rules text, plus any colors defined by its characteristic-defining abilities (see rule 604.3) or color indicator (see rule 204). Example: Bosh, Iron Golem is a legendary artifact creature with mana cost {8} and the ability “{3}{R}, Sacrifice an artifact: Bosh, Iron Golem deals damage equal to the sacrificed artifact’s mana value to any target.” Bosh’s color identity is red.
