Re: They'll all be mine in the end.
I think u should add maelstrom and mjolnir too... When u are facng heroes with illusions and summons, maelstrom/mjolnir is really good also it boosts ur attack speed too, while razor needs attack speed so bad (cuz he has that imba damage bonus from static link so balancing it with imba attack speed is okay).
Also I think, phase boots is good to if u want to be a ganker and if u don't like people evading u.
And.. I don't really agree with ur skill-build. Look, early game damage boost is really good, but u neglect movement bonus from unstable current. No one really cares about ur +200 damage when u have shitty attack speed so u don't attack really often in the early game and also, ur ms sux. When ppl see u using static link they just run. And ganking the whole game with some disablers is not a good idea, cuz Razor needs some farm imo^^.
Well... I do not say this just by theory-crafting... I play with razor quite often and I find myself frustrated when enemies stun me and run aways, while my link gets removed (unstable current is really good, that extra 100 damage "wanna-be nuke" is kinda good, some extra slow and ur imba movement speed. Sweet.) Anyway, I will try to test it once again. Who knows, maybe it really works.
Guide is good overall, well written and concise. Just correct those icons (Thrall's skill-set ^^ )
