Another deck I tried but ended up abandoning was a monowhite deck full of lifegain, removal, and my secret weapon, the
Avatar of Hope. I forget the exact list but it was something like:
4x
Path to Exile4x
Swords to Plowshares4x
Kitchen Finks4x
Avatar of Hope4x
Knight of Meadowgrain1x
Balance16x weenies, honor of the pure, spirit link, whatever
23x mana
I forget what all else it had (I must've deleted it) but I think it might've had
Spirit Link and then just some random weenies or honor of the pure or something. I might've had
Battlegrace Angel, too, but I would use
Baneslayer Angel now.
Ajani Goldmane would also be nice, but Elspeth is probably too slow. Perhaps a few shadow dudes, too, or else rely on the removal/lifegain.
Baneslayer Angel would probably be a beast if you could get him out in time.
Soul Warden might be a good addition, too.
edit: Just beat the challenge again with this deck:
Ajani Lifegain

Honor of the PureThe last match was the only really hard one. It took me 3-4 tries to get there, and then I mulled down to 5, and I was history. The next attempt I made it to the last round again and got
Soul Warden,
Knight of Meadowgrain, and
Black Lotus in the opening hand. By end of game, I had 29 life. I think this deck did a lot better than my
Master of Etherium deck did.
With Ajani, I found that I was using it every single turn for counters/vigilance, unless I had no creatures or Ajani had only 1 counter (even then, if I had a 2nd one in hand, I'd use it, play it, and use it again) so don't worry that the last ability is locked; I never used it a single time, nor did I ever even have more than the 4 original counters on Ajani at any time.
I'm pretty sure
Baneslayer Angel isn't locked, but if it is, use
Battlegrace Angel instead.
