Silver edge is redundant, just go aghs.
Solar crest is niche item for alche or any other carries that benefit a LOT from attack speed.
You want to go crimson guard/lotus orb instead of AC/shivas. These two items provide much more for dooms momentum.
Your early game items are very good, but your core items are really really bad. The only items that doom needs to be effective is (Blink, phase boots, bkb, drums). Everything else is luxury and situational.

Secondly, always add W lvl 1 to contest for rune, devour is useless and you can ask your support to nuke range creep for you if possible. You want to push out 2nd wave with W(comes off cd after contesting for rune) and go find a strong neutral creep to devour.

Additional stuff: Scorched earth pierces bkb and rage(so doom is actually a relatively good laner against lifestealer depending on neutral creep luck.
