So, Friday night, I replaced the two main Magus of the Moon with two Spellskite and replaced the two Walking Ballista with two Defense Grid.
I ended up 2-2 for the night which I attribute to two really bad matchups.
Match 1 - Loose to Mardu Pyromancer ... never saw a Spellskite enough said.
Match 2 - Win against Grixis Control - Game one, I played a turn one Rabble Master, then finished with a Slagstorm and it was over. Game two I got a turn 1 Defense Grid. This card did some serious work! Every turn opponent tried to counter something or Snap something and I was like "ok, 3 more or 6 more mana". Opponent was very frustrated and basically locked out by this card; it was amazing! Also got to use Spellskite a bit in these games, but it only saved me a few points from Bolts.
Match 3 - Loose to GWU Company - Game one I had Chalice on 1, 2, and 3, and a Bridge; he Collected Companys into two Qasali Pridemage then rushes me for like 100 points...brutal. Lost game two quickly.
Match 4 - Win against Affinity due to turn one Chalice on 1 both games.
I think the biggest takeaway from these matches for me was that the Defense Grid is awesome if you can get it down right away.
