Sharkey, Tyrant of the Shire

Activated abilities contain a colon. They're generally written "[Cost]: [Effect]." Some keywords are activated abilities; they have colons in their reminder text.

An activated mana ability is one that produces mana as it resolves, not one that costs mana to activate.

If an activated ability of a land an opponent controls references the card it's printed on by name, treat Sharkey, Tyrant of the Shire's version of that ability as though it referenced Sharkey, Tyrant of the Shire by name instead.

Sharkey, Tyrant of the Shire gains only activated abilities, excluding activated mana abilities. It doesn't gain keyword abilities (unless those keyword abilities are activated), triggered abilities, or static abilities.

Sharkey, Tyrant of the Shire's last ability uses a new template indicating that you may spend mana as though it were mana of any type to activate Sharkey, Tyrant of the Shire's abilities. The six types of mana are white, blue, black, red, green, and colorless.

Snow mana is not a type of mana. Sharkey, Tyrant of the Shire's last ability won't let you pay a snow cost using mana produced by a nonsnow source.
