Urza's Saga: Carpet of Flowers

Edition:	Urza's Saga
Type:	Enchantment
Cast:
Rarity:	U
Collector #:	240
At the beginning of each of your main phases, if you haven’t added mana with this ability this turn, you may add X mana of any one color, where X is the number of Islands target opponent controls.
Pro Tip! When blue is as powerful and popular as it has been throughout Magic's history, it's great to have a one-mana enchantment to capitalize on that. Get extra value by playing Carpet of Flowers during your first main phase so you can get mana during your second main phase.
