A tricky spell... the best thing i can come up with is to search for admonition angel and 4 lands. you have 2 admonition angels in play and 8 landfall triggers. Use the first 6 instances of admonition angel's ability to exile six things, then have the angels target each other. First your admonition angel will be exiled by your other admonition angel, then the angel in play will be exiled by the first angel, who returns to play. then the six other targets are exiled, never to return.

Depends on the use.. generally rite of replication will be better (and is easier to cast, though its 9 for kicker, all colorless + 2U), but this has other uses, especially when other permanents are in play, like oblivion ring, journey to nowhere, and various artifacts like equipment or the alara mana ones (borderpost, obelisks)

It's not the best. Ultimatum is the best but i think Clarion can be really good. That took 5 new permanent in play but the problem that you have to got it in play already.use with card that do effect when it come into play... My favourite move i do with Clarion is with 2 oblivion ring in play.
