Greetings, I made this deck to try a diffrent way of life gain. Instead of soulsister, who gains small amounts of life through the game, I added cards like Congregate, Elixir of Immortality and Riot Control to get tons of life in one swing. It's still based on Ajani's Pridemate, but instead of the "Soul Sisters", it uses Soulmender (Personal Preference) and Nyx-Fleece Ram. In the late game it has Baneslayer Angel as big creatures to slay your opponent.
Deck: http://deckbox.org/sets/869077
The main win conditions are:
+Having some Baneslayer Angel flying in.
+Getting Ajani's Pridemate big.
+Using Angelic accord to create Angels
+Play the long game with all your healings and use Mass Calcify to get rid of his defenses, so you can strike throug.
+Combo Ajani Steadfast with Angelic accord. Make an Angel, plus one Ajani onto the Angel, strike with it and Lifeling gets you another Angel.

Otherwise, as last resource, you can try to make your opponent run out of cards using your heals and Elixir of Immortality
I'm looking for opinions, as i don't actually own all the cards yet. I'm going to test it out with proxies and try to add results.

Results:
+None yet.

Thanks in advance and sorry for my bad english,

You might consider Sunbond as it will allow more triggers for your lifegain than just Ajani's Pridemate.

Modern isn't really my format so I may be wrong, but I think you are going to have problems, as this deck seems to slow to kill your apponent.

I wish you the best of luck. Hope it works out.

I have considered it before, but i couldn't just make the cut. Although I see it's potential with Riot Control and Congregate, I can't find a space in to fit it.
And yes, this deck is slow, as it focuses the mid-late game, when you can, for example, create angels and buff them with Ajani Steadfast, or have some creatures out to pass unblocable with Brave the Elements and Mass Calcify. That's what I try to differenciate from Soul Sisters.

Pridemate will only trigger for 1 +1/+1 token off any of these cards. You've traded incremental advantage and a huge beater for less controllable boosts and a smaller beater.

My personal opinion is that it won't work with the way you've set it up. Life gain in Modern won't stand up to beaters like Tarmogoyf and Archbound Ravager. Theres a reason Soul Sisters isnt even really a top tier competitive deck. Diluting one of the strongest interactions in the deck won't make you win any better!

If you're set on large life gain into a win, I'd look at something like Felidar Sovereign and Ajani, Mentor of Heroes that might at least win you the game consistently. Run it in a Bant Controller deck with stuff like temporal mastery to trigger the Upkeep at your own pace and you've got a really cool deck potentially.
