1) this deck ends up top decking alot thts why morphing jar is in there
2)sangan is in there cause it has 5 targets it can search
3)Dark eruption is a good card with kalut, sangan, gale, and blizzard dont hate till you try it
4) only 2 icarus attack cause if you play blackwings for as long as i have you know you dont always have a tribute for it and its a bad top deck
but if you wanna give advice go for it:)
