A card with a monocolored hybrid mana symbol in its mana cost is each of the colors that appears in its mana cost, regardless of what mana was spent to cast it. Thus, Advice from the Fae is blue, even if you spend six black mana to cast it.

A card with monocolored hybrid mana symbols in its mana cost has a mana value equal to the highest possible cost it could be cast for. Its mana value never changes. Thus, Advice from the Fae has a mana value of 6, even if you spend {U}{U}{U} to cast it.

If a cost includes more than one monocolored hybrid mana symbol, you can choose a different way to pay for each symbol. For example, you can pay for Advice from the Fae by spending {U}{U}{U}, {2}{U}{U}, {4}{U}, or {6}.

If an effect reduces the cost to cast a spell by an amount of generic mana, it applies to a monocolored hybrid spell only if you've chosen a method of paying for it that includes generic mana.

In a multiplayer game, compare the number of creatures you control with the number of creatures each other player controls. If any single player controls at least as many creatures as you, you get to put only one card into your hand.
