Trying to climb solo queue w/a greedy Ezreal build

It's very greedy but pays off very quickly very nicely very bigly etc.

The idea is to start off humble yet impactful and become a dream carry quickly, save CC and AoE autoattacks. I take Stormraider's Surge because all it takes to trigger it on a squishy champion mid/lategame is to E near them and land either a Q or an autoattack on them. Once it's proceed I'm extremely mobile until my E comes back off of cooldown, which if I land 2 Q's will be shortly after Stormraider's wears off which itself only has a 10 second cooldown. Stormraider's isn't for running away; it's to finish off targets and kite tanks. I look for ways to E in constantly and play around CC.

The build is almost pure damage along with some CDR and sustain/resistances. The main source of raw damage in this build is Seraph's alongside Muramana. Nothing about either of them cancels the other one out except for their mana gain and refund per cast effects so I finish them one at a time and start building AA when I have Muramana. I can't rush Gauntlet with this build because it hardly represents any more dps which is crucial for consistently triggering Stormraider's Surge on everybody.

I've tried building Duskblade first after Manamune but autoattack's with Muramana are all but wasted on tanks unless I have % arpen. Mortal Reminder or Lord Dominik's Regards are mandatory with this build.

My build order is Doran's Ring, Tear, Vamp, Manamune, Sheen/Hexdrinker, Mortal Reminder/Lord Dominik's Regards, Ninja Tabi/Mercury Treads, Archangel's Staff, Death's Dance, Iceborn Guantlet/Maw of Malmortius.

My runes are AD marks, armor runes and 20% worth of CDR glyphs and quints so that I'm not forced to build any.

I ban Akali because she's a hard counter lol.

Tips/opinions?
