PeliKan's referring to Drone, the vanilla 6/6 for 2 that GI got in Order. Adaptive Construct is just plain better, even having an identical morale cost. Does seem like it would have made sense to give it a higher morale cost or slightly lower its base stats while improving the benefit of overcharge (for example instead of a 6/6 that gets +2/+2 make it a 6/5 that gets +3/+3).
Ninja'd. Do people still use Drone? I saw them before but now GI mostly seems to just go with construct and the infected drone for its 2drops.
