My main start and it worked all three rounds was the following:
Rd 1 (20) - Crystal & either Asyran Cleric or Disciple of Radiance
Rd 2 (21) - Temple & another cleric or Disciple
Rd 3 (17) - Deploy Ehren, Harmonize Temple, and summon Broken Wing Angel to begin the healing on Ehren.
Rd 4 (15) - Deploy Sharpshooter or White Cloak, and then my casting depended on how well Ehren got healed but I either brought out the Renewing Spring or Hand of Bim-Shalla and then
And then I probably started enchanting things with Blessed Focus or brought out the Crown and armoring creatures up to do two things, help them out and save mana so I can start bringing out the bigger guns from the Temple (Brogan, Guardian Angel, Archer, Aurora, etc).
Against the Druid in my 2nd match, Ehren got only one 1 healing from the Broken Wing Angel and then only 2 from the Renewing Spring so I had a backup plan there and it seemingly worked since I also knew it'd be a long match that came down to life...I threw a life link on Ehren and then put on a Regrowth Belt and Sunfire Amulet which healed him, healed myself, and started growing my life as well.
Against the Necro in the finals, I thought I was done. I was down to 4 remaining life, there was a Deathlock on the board but the Necro was only at one remaining life but I had Enfeeble on me and the Necro was 2 zones away and the only action I had left was my own. I knew a Drain Soul was coming if I couldn't figure something out and then I remembered something I ALWAYS forget. Restore. I removed the Tainted from a previous Drain Soul and got me those 6 life back and then I had enough creatures that I was able to swarm towards the Necro in the next round while keeping myself protected from ranged attacks with a Guardian Angel.
If anyone wants anymore specifics, let me know.
