Techies/Counters

Heroes with summons

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


 * Also makes base defense extremely difficult late game. Especially since he can teleport behind your minestacks.


 * Sending creeps to defuse Land Mines.


 * Sending Wolves to defuse Land Mines.


 * Sending Conjure Image to defuse Land Mines.


 * Sending Mirror Image to defuse Land Mines.


 * Sending creeps to defuse Land Mines.


 * Sending Hawk to explore where Techies has planted mines and Boar to defuse Land Mines.


 * Sending Tempest Double to defuse Land Mines.


 * Sending Illusion from Disruption to defuse Land Mines.


 * Sending Illusion from Doppelganger or Juxtapose to defuse Land Mines.

Nukers

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


 * His rearm can disable and kill Techies in a short time.


 * After she uses Scepter of Divinity and her stun, Laguna Blade will kill Techies before he has the chance to suicide.


 * With two disables, Techies can't do anything and will die from a Finger of Death.


 * Snowball stuns Techies and Walrus Punch would be the finishing blow.


 * Duel disables techies completely and due to his pathetic attack damage, he becomes an easy kill for her.

His Astral imprisonment will capture Techies to be targeted or kill him with Sanity's Eclipse.


 * Flux makes Techies helpless and Necronomicon can deal enough damage to kill techies and render his suicide ability useless, as the minions burn his mana in no time.


 * His disruption and Demonic Purge will make Techies helpless.


 * He can spam Dagon at a Sprouted Techies. Nature's Wrath with Aghanim's Scepter is ok to look for Techies and defuse his Land Mines.


 * His silence at night is long enough to kill Techies before he can suicide.


 * Last Word and Silence Global shut down Techies's suicide ability.

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 and the more she traps you with duels the more you'll be accused of feeding.


 * Can hex, stun and burst techies down easily.


 * Shackles are devastating in lane versus Techies.


 * Last Word and Silence Global shut down Techies's suicide ability.


 * Can stun, silence and slow Techies long enough to give his allies enough time to kill Techies.


 * If the arrow hits you, you'll be stunned for an eternity leaving you vulnerable.


 * Storm Hammer can almost kill you as well as stun you to prevent suicide. Not to mention his ridiculous attack damage to finish Techies off.

Slows

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


 * Stuns for days.


 * Slows for days.


 * Excruciatingly annoying to lane against since it's almost impossible to get close enough to suicide without losing most of your health. Venomancer's Plague can prevent Techies to plant bomb in secret spot.

Special Mention

 * Impossible to deal with early game since her Refraction blocks almost all mine damage - you need way more mines than normal to kill her. Also slows AND nukes - a nightmarish 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 game. Slows, silences, moves extremely quickly, is very tanky and once he gets Aghs and Gem can completely shut down all your defenses. Almost an instant loss if the player is good.


 * Similar to Night Stalker, a Keeper of the Light with Aghs and Gem can spot any mines that may affect him or his teammates.


 * 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.


 * 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.


 * Phantasm can trick Techies to press Remote mines because sometimes Nessaj has extra Phantasm illusion which can trick techies into thinking that the main Chaos Knight is in the cluster.


 * Primal roar is enough to stun Techies who can later be killed with his boar, Wild axes and Necronomicon units.


 * Not only can spiderlings defuse bombs. Her sneakiness is hard for Techies to suicide and get a kill.

Items

 * Necronomicon : Every level is useful for defusing mines. Especially Level 3, Necronomicon Warrior's True Sight will reveal all mines.
 * Gem of True Sight
 * Scythe Of Vyse makes Techies unable to act(except drag remote mine on the map and press 'Q') so he can be targeted after or while hexed.
 * Orchid Malevolence or Bloodthorn silence Techies long enough to be killed. Beware though as he can still lead you into his mines.
 * Black King Bar users take no damage from Remote Mines and don't get stunned.
 * Ghost Scepter and Ethereal Blade prevent physical damage from Land Mines and Suicide Squad Attack. Also Pugna's Decrepify performs the same function as a Ghost Scepter and Ethereal Blade.

Good against...

 * During the early-middle game he tries to gank and explore for his team. This makes him an easy target and an unsuspecting prey. Until he has Black King Bar or Orchid Malevolence, he's a piece of cake for Techies.


 * Same as above


 * Ember Spirit nowadays can be played as a pusher so he won't care about mines even if the cleave from Battle Fury can destroy mines. Exploiting this carelessness, Techies can trigger Remote Mines before he escapes with his Fire Remnant.


 * Soft, and tends to run around in the lane; thus more likely to run over Land mines.


 * Morphling loves to split-push, and will usually walk over Remote mines with max or high Agility morph making him an easy kill.

Others

 * Anyone who's squishy.
 * Players who don't ward.
 * Riki: same reason as other invisible heroes like Bounty Hunter and Clinkz.
 * Nyx Assassin because his Carapace Skill never reflects Techies' mines and his sneaky gameplay without Gem of True Sight can lead him to his death into mines. Except if he has a Ghost Scepter and he runs into them. By the way, Nyx is the best Techies counter because after he attacks with Vendetta, he can stun and use Ethereal Blade with Dagon to instagib Techies (Except when Techies is tanky enought to commit suicide with a Bloodstone).
 * Bloodseeker: because he is greedy when tries to kill enemies who have the Thrist debuff. So Land Mine can lure Bloodseeker to his death.

Works well with...

 * Nether Swap works well with Land Mines.


 * Meat Hook delivers enemy to Land Mines.


 * Chakra Magic can help bolster Techies' rather bleak mana pool in the late game, while also shaving off a few seconds of cooldown.
 * Recall can also help encourage split pushing, by allowing you to set up mines in one lane, then be teleported back to the fight.
 * Blinding Light can push enemies out of position and into your mines.


 * Reason


 * Batrider's ultimate (Flaming Lasso) allows him to drag enemy heroes towards bombs.

Others

 * Magnus : Reverse Polarity and Skewer enemies into mines.
 * Enigma : Draw people closer to mines.
 * Dark Seer : Draw people closer to mines.
