Hi all! Found this forum recently and decided I ought to join proper. Apologies if this is the wrong place... I assume Legacy is right because pretty sure this deck has cards too old for Modern, although I'd love to get it into Modern.
Now, you've already read the title. I know, I know. Life Gain. Not very competitive. So this might almost be better suited for the Casual forum... but I'm convinced it can be at least somewhat viable! I've been playing around with the following...
So far it works fairly well. Once it gets going, it gets great momentum, but it can be slow to start. Earlier fliers in particular can be nasty. But it's got multiple win conditions:
-A big aggro smack. The Pridemates can get huge, as well as the Avatar of course. I added the Warhammer to give some trample so they don't just chump blocked.
-Chalice of Life (and Death) if I can't hit them for some reason.
-Lifegain itself with Test of Endurance or Felidar Soverign
A few questions off the top of my head...
Mother of Runes is great... but wasted here?
Should I have more removal (Swords, Path, etc)?
Should I bother with the Chalices?
Your deck most highly resembles a deck called Soul Sisters. You can google for something like "mtg legacy soul sisters" and get a good number of deck lists to check out. There should be a rather large primer in the modern section of these forums, and maybe here in legacy as well. Either way, you probably want to try and steer your list in that direction.
