I disagree with how it is now. But I like the idea of adding Might and Magic ancient objects. The "Ancient Weaponry" would be the Blaster pistol, or blaster rifle, and would either increase the damage of the next attack or add a large quantity of recruit (arms). It would also be rare, as the only way in the games to get such items would be to storm the Control Center, or other strongly defended places. The android(s) would need a "very rare" tag or something equivalent, considering how powerful just the "Patrol" units were. I recommend having a rare summoning card that discards another rare (one that could somehow capture a Unit) to draw an android or a defender/terminator unit. The unit/android would not be available in the deck lists, just from the rare summon card. The summoning card itself could be many things, but probably a map/plans or an "ancient control device". The android itself could be programmed to do multiple things (attack, stay in castle, defend border), but I don't know how one would balance it's stats. A terminator unit was on par with a gold dragon though, so that would be a start.
