Gaea's Cradle and Serra's Sanctum

[(nameless one)]

Hey guys,

If I tap Gaea's Cradle for mana and I currently do not control any creatures, would it produce mana?

Also, same thing with Serra's Sanctum, but only with enchantments.

It count's the creatures/enchantments you control on resolution. If you control zero creatures/enchantments it produces zero mana.

Cool

Thanks!
