He travels with your army taking up 10 spaces. As your normal army is defeated you send in the summoner who pauses similar to a witch and ressurects the troops that have died in the area around him (tombstones). He only does 10,15,20 dps but ressurects troops in the area similar to a witch at similar intervals, every 5 seconds. He is limited to reviving 5 spaces at lvl 1 ,10 spaces at a time at level 2 (10 archers, 2 wiz & 2 archers, 2 giants, etc.). At level 3 it bumps to 15. He only has 75,100,125 hit points so he is vulnerable to strong single target defenses. However similar to a witch he will be targeted last after the summoned troops die.
Strategy
As opposed to sending a healer to follow your giants around you can send summoner that would ressurect fallen giants along the way.
Also send him along with wiz/ barching troops for a slightly more effective attack.
Alternatives
Summons fewer troops
Only DE troops revived
Requires more housing space
Let me know what you guys think.
