Text:

: Add {C}.
, : Add one mana of any color in your commander's color identity. If you spend this mana to cast your commander, it enters the battlefield with a number of additional +1/+1 counters on it equal to the number of times it's been cast from the command zone this game.

Rulings:

• 11/10/2020 If you have two commanders, the last ability adds one mana of any color in their combined color identities.
• 11/10/2020 If your commander is a card that has no colors in its color identity, Opal Palace’s last ability produces no mana. It doesn’t produce <img src="/Handlers/Image.ashx?size=small&amp;name=C&amp;type=symbol" alt="Colorless" align="absbottom" />.
• 11/10/2020 If you don’t have a commander, Opal Palace’s last ability produces no mana.
• 11/10/2020 The “number of times it’s been cast from the command zone” includes the most recent time. For example, the first time you cast your commander from the command zone in a game, if you spent mana from Opal Palace’s last ability to do so, it will enter the battlefield with a +1/+1 counter.
• 11/10/2020 If Opal Palace’s last ability produces two mana (most likely due to Mana Reflection) and you spend them to cast a commander, that commander enters with two counters for each time it’s been cast from the command zone this game.
