To be honest I have always seen this card, and have previously owned it, but never used it. The stat line seems weak for something t3 especially when going frost/shadow, with the lost grigori and stuff, hell you could probably put harvester over this. It seems to want to have synergy with structures. The green affinity - "Unit considerably gains in strength when positioned within a 20m radius around a friendly structure. It then has a long range of 50m and every blast deals 180 damage to enemies in a 15m radius around the target, up to 270 in total. Additionally, the unit will regenerate 25 life points every second." The purple affinity - "Unit considerably gains in strength when positioned within a 20m radius around a friendly structure. It then has a long range of 50m and every blast deals 180 damage to enemies in a 15m radius around the target, up to 270 in total. Additionally, 25% of damage dealt by the unit will be added to its life points." I just do not see the value in this card, in all scenarios. It can easily be squashed or blown up.
