This is a life-gain, deck which has evolved and changed alot throughout the years.
It has gone through the phases of a pure life-gain, to more of an angelic token deck and now in this third iteration I've tried to return to a more Life-gain-heavy deck with an added focus on +1/+1 counters mixed in there.
The "main" combo persists of Rhox Faithmender + Cradle of Vitality (or Nykthos Paragon for full sauce) and then buffing up either Rhox himself or one of the many angels this deck will spawn (or full-sauce buff-up everyone).
Nyx-Fleece Ram + Bishop of Wings gives a much needed early game defense until you reach 4+ mana mark, when you can begin spawning Angels and getting Rhox on the board.
Court of Grace + Bishop of Wings + Archangel of Thune will provide both a crazy amount of +1/+1 counters, 4/4 angels and lifegain.
Ajani Goldmane gives the deck a very nasty presence on the board, caus' noone would want the Avatar + Cradle of Vitality to go off and you add Celestial Mantle to the mix, and you have an almost unstoppable force.
Swords to Plowshares gives you control and removal, and makes sure that you're not taken aback by something really nasty like a turn 3 Emrakrul.. (You can also use Path to Exile, but I'd rather give my opponent life than mana)
Felidar Sovereign gives a fun win condition, that you could use if everything else fails or you can't through to your opponent.
