My sideboard was:
4 leyline of the void
3 leyline of singularity
4 pithing needle
2 hurkyl's recall
2 threads of disloialty
But i'm not sure that is the best side for this deck, I'll try some changes the next time !
The long deck against I played was a sort of old style long, in fact i never had the possibility to drain a spell cauz it was too fast, the only match I won I had a broken start with a turn one land mox and merchant for fow and a turn 2 tinker for colossus with a time walk in my hand

!
The mana base was really solid,i never had color screw problems, even vs artifacts...Instead of adding another blue source i suggest to add a fetch land , beacuse is very nice with crucible and fastbond

!
If you want, i'll write a little report soon !
I'm thibking about this possible changes (i'm talking about the list with gifts tinker colossus and mystical instead of 4 gush) :
- 4 ak
- 1 intuition
+4 gush
+1 deep analysis
But i think that this way the match up vs artifacts will be a little worse...
What do you think about this ?
