Ultrax dragons on impossible - no casualties/5 units

[loreangelicus]

Ultrax dragon battles on impossible, no casualties using 5 units. Screenshots attached, depicting the 3 dragon battles, 3 screenshots each showing these:

shot 1: start of battle
shot 2: battle dominated; all "lost" units resurrected
shot 3: no-casualties victory

The key in each battle is identifying the "weakest link" and wiping out everything else; then use LIFE totems and ice ball to keep it busy. Not as easy as you think as the weakest links in two of the three battles are green dragons and red dragons.
