Has Round 4 vault been updated?
I was thinking of something like this against light:
4vi 4vi 4vi 4vi 4vl 4vl 4vl 5f9 5f9 5f9 5f9 5f9 5f9 5fc 5fc 5fc 5fc 5fc 5fc 5gi 5gi 5gi 5gi 5gi 5gi 5l9 5l9 5l9 5l9 5l9
The EQ deck would be pretty good too, but I wouldn't use it with pillars. I'm not sure if we have EQs though.
