Played a Legacy monthly today, finished 4-1

R1 2-0 over Eldrazi. Both games he starts with turn 1 amethyst, but I power through both turns on t3 anyway (g1 on a mull to 5).

R2 2-0 over RG Lands. G1 I have a turn 2 token. G2 I extract his loams, have wasteland covered with needle and have a window on my 6th turn.

R3 2-0 win vs UR Painter. G1 turn 2 token. G2 is a long grindfest in which I manage to combo.

R4 0-2 loss vs Death and Taxes. G1 I have 3 needles but no NotW for Swords and can't combo, die to beats. G2 I strip his hand, and wipe his board but don't have any follow-up and eventually die.

R5 2-1 over Rg Lands. G1 bog away 3 loams, needle his wasteland, it's a long grind in which I eventually manage to come out on top. G2 I mull to 6 and keep a very reactive hand. In spite of me fighting, I end up manascrewed and he comboes. G3 in the 3rd turn of extra turns he is forced to go for it (I'm 3-1, he is 2-1-1 and needs the win). He crop rotates for the combo , takes his turn, attacks, I crop rotate for the combo, block. Untap win in the 5th turn. A draw would've locked t8 too (but not for him).

Top 8 split.

Had some tough mulligan decisions but was happy w/ my play overall barring a few mistakes. Unfortunately no Miracles, which I do expect to face in a Legacy Invational I'm playing in two weeks in my country.
Has anyone considered Nissa, Vital Force for this matchup? She seems to be doing a lot of things we all want in the matchup.
+1 attack for five.
-2 return a permanent
ult is card advantage

I'm thinking of testing her.
