New Trap: Snake Pit

The Snake pit is the same size as a tesla and is upgradable but I will not write down levels and stuff.
Trigger Radius: 4 tiles
Targets: Ground
The Snake pit originally spews three snakes(upgradable) and costs 1k to be rearmed
Snake
Poisoned Units per second: 1
HP: 150
Favorite Target: Wiz and Archer
Damage Type: Single Target
Targets: Ground
Speed: 28
Snake's Poison does 10 DPS and until the snakes are killed they continue to poison more units. They are unlocked at Th 5
All snake stats are upgradable. This would be affective for taking out the ranged units in a raid. Since they go straight for the wiz and archers that are probably hiding behind Giants or golems.

I need feed back to see if this is a good idea or how I can improve thx

Please no. The skeleton trap was enough of a distraction for the troops, if your idea would also be included then a GOWIPE attack will never get to target the Town Hall because these small troops will just keep them busy forever.
