Elemental Tempo Mage (Keleseth + Spiteful Summoner)

This deck is very strong and synergic! I'm already rank 4 from 8 by playing this night. The only card I didn't played with is Witch's Cauldrons, cause I don't have, I was using the Tanglefur Mystic and was working very well, but I think the cauldron should be better. Toki, Time Tinker maybe work well in the deck too but it already have two spiteful as six...
