Tested at last two FNM. The original deck went well againist lockdown control mill (isochron scepter with silence and etheral haze). I easily countered that with azorius guildmage and his counter target activated ability. Even if he manages to isochron with silence berfore my guildmage, i just waited to have enough mana and then casted dispel and guildmage.
I also managed to take downn mono green ramp deck with big creatures. Again, thanks to my guildmage with tap target creature. The rest i blocked with my big big walls with the help of dramatic rescues and inaction injunction. I took him down from 34 hp while I was only at 4hp. He had no chance to get that 4 dmg to me for like 8 turns.
The last deck I played againist was mass artifacts and cheap creatures with "when this enters the battlefield, sacrifice it, unless you return artifact you control to your hand". It was easy with ornithopters and memnites. I had no chance to block 8 creatures on turn 3, where every attacked for one or two hp.
So I decided to add some mass destruction in. I got detention sphere and supreme verdict, which turned out to be very useful againist classic modern miracle deck. I just wiped the board of 8 4/4 angel tokens (twice entreat the angels, 1 on miracle) and then finish my opponent off with celestial collonade and azorius keyrune.
So after that I decided to move training grounds to sideboard and I am not sure, if they manage to survive in this deck. I need more supreme verdicts and maybe another counterspells. I wonder about spell pierce.
