Since this was the original design of the unit i have remade it.
The current zurgo is the old design of the orc leader (that i have remade since I really disliked it and tought didn't deserve to be in game)
I also think that noone uses zurgo right now since there is no point.
A growing unit like zurgo should have a higher survivability, otherwise it is better to produce a unit that is powerful from the start or a swarm of cheaper units (that will die easily but you won't cry on them).
Those are my suggestions (also based on the card effects).
Zurgo (in the card) is indestructible during your turn. If possible (Daniel will knows) it should then be immune to poison, area effects dealt from your units and counterattacks.
Assuming it is not easy to obtain i would at least leave the immunity to counters.
Also zurgo (always in the card) receives a +1/+1 that is a +1 attack and +1 contitution. So zurgo should also receive hit points and/or armor by its effect
Also Its starting stats are very low so i would raise them of a good amount and raise its cost to 4
