Hallowed Fountain (ECL)

Land — Plains Island

({T}: Add {W} or {U}.) As this land enters, you may pay 2 life. If you don't, it enters tapped.

Essential dual land for blue-white strategies across all formats. Hallowed Fountain provides untapped mana at the cost of 2 life, a negligible price in most matchups and a critical advantage in tempo-sensitive decks where entering tapped would derail your curve. It's a four-of in competitive Modern and Pioneer control, a staple in Commander, and legal in every constructed format that matters. If you're building anything with both blue and white, this is the land you want.
