An example game I played with this deck:
Clearly, this deck cranks out a ton of life. This makes it very easy to recover from frequent burns, enchantment removals, or even board wipes. Below is a card breakdown showing you exactly how and when to use each.
Breakdown
The general goal with this deck is to have any creature with lifelink on the board and enchant it with Sunbond or target it with Cradle of Vitality when it does damage. In this way, your lifelink creature doubles in size each time it attacks. Lone Rider
and Aerial Responder are great examples of cards to enchant due to the first strike/trample and vigilance, respectively.
Rhox Faithmender and Boon Reflection exist to increase those +1/+1 gains even more. The great thing about doubling life gained is that it scales exponentially, not linearly. So 1 Rhox means x2 life, 2 Rhox means x4 life, 3 Rhox means x8 life. This can and does add up super quickly.
Kabira Crossroads looks like an early game penalty, but really this land is exactly what you need so that by turn 3 you can have Soul Warden and Kabira Crossroads combine to give you 3 life and transform Lone Rider
. This makes for some very good early power.
Most of the lifelink creatures in this deck have first strike. You can swap these out for your favorite lifelink creatures as you want; however, this was done so that creatures with deathtouch can be safely ignored throughout the game.
Oblivion Ring and Angelic Edict are in here as a bit of control. They can be used to remove the other player's threats from the board. They are also useful for retrieving big creatures that have been Arrested or Spell Quellered away from you.
Spirit Link is a very handy and versatile card. This is ideal for giving your creatures double lifelink; although, it can also be used to nullify a big threat on the opponent's side. He can't hurt you if you gain life equal to the damage he does.
Gleam of Authority is a bit more situational than most in this deck, but in the right moment can make a big difference. Primarily, this card is nice because it gives vigilance and can start off a game with a bit of slow +1/+1 counters to tide you over until the big spells come out. The best time for this card, though, is alongside a massive creature with Sunbond on it. As the Sunbonded creature gains counters so will the one with Gleam and you can scale two lifelink creatures simultaneously.
