at start i wanna say that my english sux like hell so propably u will all time think "o lol what a moron, learn english" but... i rly dont care ;p
this is guide how to play as Morde, not teaching english ;p

in my opinion, if i play as morde only 1 week and i have 12 wins and 3 loose on ranked games i think he is good champ.
(already 2 quadras)

he is very good farmer, is hard for kill, and even tanky items he have "Tones of DMG"

well,
Marks: m.pen i think no need explain
Seals: hp regen is very important for morde, cause of hp cost on his spells
Glyphs: no need much ap at start, trust me, its enought
Quint: flat hp regen (same reason like on Seals)

on this rune setup i have lvl 1 35hp regen /5sec
(with regrowth pendant)
and i can easy spam my spells

thnx to Seals hp reg / lvl
i can hold my lane for very long time

23/7/0
why?

cause i have def runes i need get some dmg
improove all dmg that is possible
u will see that u will made still nice dmg and u will be protected by ur "iron man" passive.

just spam E all time.

hp regen at start is very important for morde.
when u get m.resi and finnaly full FoN, u will be allmost immortal on mid lane.
just care about gank.
nice dmg and m.resi + nice hp regen.

when u get warmog, ur hp regen will be extrem high, more hp, more spell spam, and still with rly nice dmg

with sunfire cape... armor, m.resi, tones of hp and hp regen, aura from sunfire + ur skills,
just overfarmed morde

finnaly we start buy AP items for spellvamp.
Hextech and WoA,
pro dmg, spellvamp and lifesteal
IMMORTAL MORDE

E, most important cause of easy farm
Q, well, better dmg than E if u hit only 1 target, but still prefer max E
W, just 1 piont and max at last.

many ppl ask, why no flash?

cause tanky morde no need flash for run or get kill
she use ghost and dive cause.... cause he can !
mobility for morde is (imo) very important.

flash is also good, but... ghost is better

well, i know hre is no many colors, no links etc.
but trust me, 12 wins 3 loose (and rly not cause of my bad game) on ranked.
2 quadras 4v1
i cant belive of that much luck ;)


and remember...
... enemy carry is best player in ur team.
6v4
