Thanks to everyone for comments and advice.
I didn't create the boros /
naya archetype as I would have tested it for years.
I think that : in the first game against affinity or against any leyline or chalice is much stronger this setting.
I know boros and helix are very strong but now, together with kolagan's help I can win the 1 game, things they can't expect.
That's why I did 6-1 the other night...
Next time, in the deck there will be the integration of
tarmogoyf.
