Everybody has probly figured this "combo" out already, and think it's so 
obvious they don't even post something about it. Oh well, here it is: 

Use Desalation Angel with the kicker, then as a fast effect, sac all of the 
lands you would be losing with Overgrown Estate. You will gain at least 
twenty-one life forhaving just enough land to play the kicked Angel. Then use 
Elfhame Sanctuary to recover land and play annother Angel.
