Strategy
Use Arcane Curse when you expect opponents to cast a spell.
Clicking Glaives of Wisdom on an enemy hero doesn't draw creep aggro.
To steal intelligence from a dying hero, you have to get the kill, or have an active debuff, or be within 925 units of them.
Combining Arcane Curse with the Last Word silence does a lot of damage.
Be aware of what happens on the map, so you can use Global Silence when needed.
Using Global Silence defensively is fine, but ideally use it during fights. Make moves when it is off cooldown.
Many items dispel Global Silence. Be patient and don't waste it at the start of a fight.
Counter Strategy
Glaives of Wisdom are great for harassing as 
Silencer doesn't pull aggro and the damage ramps up.
Silencer's Arcane Curse lasts longer and does more damage if you cast a spell while under the effect of it.
Global Silence has a long cooldown. Look to fight after it was used.
Items that provide dispel are great against Silencer's silences.
