I suggest optimising the Fire and Light decks as we did with Death. The best Light rush is generally considered to be this, a Pegasus rush: http://elementscommunity.org/forum/index.php/topic,12931.0.html
As for Fire, if we want to avoid Immolation rushes or pendulums, the simplest deck would be 6 Phoenixes, 6 Dragons and a Short Sword. Phoenixes help a lot against the new Elders and all AI by absorbing CC.
Since the Elders and AI have been updated, I think it'd be great if we could improve all the decks here, as it's a very useful thread. I'm less sure on how to improve the Time deck without going into other elements, but the monodragon rush works alright, I suppose.
I actually avoided a Pegasus deck, for the sole reason that the deck is very vulnerable to Reverse Time, Devourers, and Maxwell's Demons. Believe me, I tested a LOT of different deck types before I settled on that one. I have never been happy with it, but now that there is a completely new batch of level 3 opponents, I will have to go back to the drawing board with many of these decks anyway. Coincidentally, I was contemplating a Pegasus build once I saw the new level 3 metagame. I will test for a guide soon.
Immolation is a fine choice now, because it doesn't cost much. It used to cost almost as much electrum as a dragon, which is why I chose to leave it out of my guide for Fire. Like the other guides, it is time for yet another revisit to bring the thread up to date.
