I love on-use trinkets and I highly recommend collecting a bunch of them, like the ones shown above (I carry all of those on me at all times, btw!). Having the right trinket for the right enemy is a big deal. No matter how good a static trinket like Drake Fang might be seem, it just can't compare with having the right utility trinket at the right time. I talk about some tricks and tactics concerning these trinkets below.

The Guardian Summoning Trinkets: can chase people out of stealth; are very troublesome for casters due to the spell pushback they cause; can keep your enemy from bandaging when they put you into a crowd control; are useful as anti-sap if you remain in Ghost Wolf form until the Rogue has finished using Cheapshop, Gouge, and Kidney Shot then activate one while still in Ghost Wolf form.
The Poison Trinkets: can be troublesome for Rogues because they destealth them; can be troublesome for anyone who wants to bandage and has no counter to the DoT.
The Burrower's Shell: prevents Death Coil from healing the Warlock if Death Coil's damage gets absorbed by it; when combined with lots of health and a grenade can allow you to survive Counterspells; rage starves Warriors.
Eye of Moam: is incredibly useful when fighting Demonology Warlocks who have high resistances; boosts the damage of Flametongue significantly (and unlike spellpower trinkets, it should continue to do so even after Flametongue's scaling gets fixed).
Gnomish Cloaking Device: can be used in combat, which makes it pretty good for doing things like avoiding Sheep.
Gyrofreeze Ice Reflector: can freeze Hunters in their own trap.
Ultra-Flash Shadow Reflector: can be used against Warlocks who have felhunter out to give yourself 5 seconds of time to heal without the felhunter silencing you, or the Warlock interrupting with a Fear or Death Coil.
Shard of the Fallen Star: causes spell pushback which can help you delay a spell long enough for Earth Shock to be off cooldown; is good for burst damage when trying to finish off someone before they can heal (or bubble, in the case of Paladins); has a longer range than Charge, so can put Warriors into combat and keep them from Charging.
Loatheb's Reflection: can give you a fair chance at resisting Freezing Trap, especially if you also use Frost Resistance Totem.
Heart of Noxxion: is useful for when you're trying to kite a Rogue but don't want to leave Ghost Wolf form.
Nifty Stopwatch + Gyrofreeze Ice Reflector: this combination can make you very deadly to Mages for a short period, as they won't be able to halt you (unless they have Blast Wave), and you'll quickly get into melee range even if they Blink.
Ultra-Flash Shadow Reflector + Hyper Radiant Flame Reflector: this combination is amusing to use right after a Destruction Warlock's Seduction ends and most of his bursty spells get reflected back.
The Burrower's Shell + Defiler's Talisman: this combination will allow you to absorb 1500 points of physical damage, which can work very well against a Rogue bursting you.
