Lifelink decks are just cool; it's a battle against a lifelink deck to smash it to bits as quickly as you can before the deck starts gaining so much life that you just cannot stand a chance of winning. Plus lifelink is a very cool mechanic as well :)

Originally the deck had Ajani Sunstriker and Markov Patrician in. I dropped both of these in favour of more Rhox Faithmender; this guy lets you gain double life. I also wasn't too impressed with the Markov Patrician and instead added the cards taken from this deck into my WIP Vampire deck, increasing the existing number of that card in that deck.
Firstly, not all creatures have lifelink - Goldenglow Moth and Cathedral Sanctifier don't have lifelink, but they both give me life; Goldenglow Moth gives me 4 life when it blocks (only a 0/1) and Cathedral Sanctifier gives me 3 life when the card enters the battlefield. When combo'd with Rhox Faithmender these cards can give me some significant life increase! To combo them again I have added Disentomb
