Techies/Counters

Heroes with summons

 * These heroes can easily destroy your traps in the early game by running their summons over them - they become much less annoying once you hit 6.


 * Also makes base defence extremely difficult late game - especially since he can teleport behind your minestacks

Nukers

 * These heroes can kill you extremely quickly before you get the chance to suicide

Silences and lockdown

 * These heroes stop you from getting your suicide off by keeping you stunned or silenced


 * Can prevent you from suiciding with Duel - makes laning much harder


 * Shackles are devastating in lane versus Techies


 * If the arrow hits you, you're dead.


 * Storm Hammer can almost kill you as well as stunning

Slows

 * These heroes can stop you from getting close enough to suicide for a kill in lane


 * Excruciatingly annoying to lane against since it's almost impossible to get close enough to suicide without losing most of your health

Special Mention

 * Impossible to deal with early game since her Refraction blocks almost all mine damage - you need vastly more mines than normal to kill her. Also slows AND nukes - a nightmare combo. The good part is that if she tries to hide you can drop mines on her or suicide in her face.


 * The hardest counter to Techies in DOTA 2. Slows, silences, moves extremely quickly, is very tanky and once he gets Aghs and Gem can completely shut down all your defenses without even trying. Almost an instant loss if the player is good.


 * Extremely good at removing your mines because of his true sight. Can damage you at range as well.

Others

 * Two lives, twice as many mines needed! Also very tanky and has a nice stun/slow.


 * Arc Warden


 * Difficult to kill - however if you blow up mines before his ult activates and when he has low health (with aghs+level 3) you can kill him without actually triggering it.


 * Chaos Knight
 * Beastmaster

Items

 * Necronomicon
 * Gem of True Sight

Good against...

 * At the early-middle game he try to ganking and explore for team, so he won't expect that bomb has planted


 * Same as above


 * Ember Spirit nowaday can play as pusher so he won't care about bomb even cleave of Battle Fury can destroy bomb. With this careless, Techies can remote bomb before he escape with his fire remnant.


 * Reason


 * Morphling mostly set more agility when not war. With few armor and hp, Techies can kill him before he escape.
