High elo players, please give a bronze some tips.
Tl;dr: every build I tried was unsuccessful. I'd like to know how to itemize more efficiently. My playstyle is generally play passive early and focus cs, push objectives, and help laner once I build power.
I just played a game against Voli top as Mord (surprised?), and here's how my landing phase went:
(Was trying mobility quints on Mord this game) -focused farm -poke with e and w -got first blood against voli -immediately gank ed by yi -my jungler comes -I kill yi -voli TPS back to lane, throws me back under tower, kills me. -I go back into lane, voli and I get ult, voli ccs me, ult me and melts me. -I see he had MR and AD, so I build an AD item and Magic Penetration (Duskblade for if he would later build armor and high AD in case Magic Pen didn't work, Magic Pen was Liandries) -Commenced to get shredded by Voli and his ult, built Boots of Swiftness much earlier to not be slowed as much. -yi and voli take tower. -I take enemy top tower while voli is busy bot side. -Destroyed by Voli again. -Seeing the enemies where mostly AD, I stack armor. I end up having Thornmail, Randuins, Zoynayas, Deadmans, Boots, and Liandries. -Still melted later, and could barely 1 vs 1 yi defending inhibitor tower(not that I think he's OP). -With dragon ghost, I had 4300 hp and a bunch of armor plus dragon, and was still melted in teamfights. -Traded Randuins for Rylias. -Switched to juggernaut build: Steraks, Deadmans, Rylias, Liandries, Boots, still melted.
Every full build I tried failed, even the armor stacking with thornmail. I had over 300 armor and over 3 k hp without dragon!
Maybe it's because I was a bronze player, and I'm terrible, but all game voli focused me, threw me around, and was melted afterwards no matter what build I had-- pure tank, juggernaut, tanky bruiser, high AP.
Tips and critiques from high elo Mordekaiser mains are very much welcome.
And I have level 7 mastery on Mord, but I feel tips to itemizing would help me get back out of bronze this season.
: a bunch of AP scaling, HP pool to help with the shield and most of all the slow helping not getting kited. I think it's pretty much core, not much to explain there.
: AP scaling, huge burst (Protobelt is actually kinda OP atm and Riot seems to think the opposite), cdr is nice (you'd like to be capped with morde but there are sadly few items that give cdr and stats that Morde wants)
: THE MAGIC RESIST SHRED. Forget about the MR (though it's good) this item is made for squishy killing. it reduces the mr of your opponent by a lot making it easy to crush low magic resist targets ESPECIALLY SINCE Morde's damage is all magical. He has AD ratios as well, but the abilities deal MAGIC damage. Consider this when thinking about runes (magic pen seem very good), and potentially even get sorcerer boots.
: health for the passive, and more magic penetration, also synergy with rylais.
: since you have both AD and AP scalings, an item giving both is pretty good. Also the slow, and adds a new AP scaling and sustain based on your damage output, so it has higher synergy with high damage/AP builds.
( <- weak right now, but the stats do synergize well so if the item was slightly better statwise it'd be great for morde)
for magic resist i already talked about 
(synergy with healing, health and cdr !)
or 
on Morde as an experience thinking it would be pretty good for his Q, since the high attackspeed and the CDR would allow to spam it, but I haven't had much success (especially since it's mostly good for the Q and early game maxing W is stronger). Maybe try it as a lategame purchase if you have a tanky build otherwise, could actually work out (and it grants nice mobility)
