Azir + Renekton + Nasus Ascended Sun Disc

This is the best sun disc deck I've been able to make. It's still not good enough for any type of competitive play, but it's a lot of fun for grinding against the AI or just meme'ing with your friends.

The secret sauce is simply pouring stats on your champions. 3x Xenotype Researchers, 3x Golden Ambassador, and 2x Siphoning Strike should help with that goal. If you have a Xenotype in hand, try to save your Preservarium and Aspiring Chronomancer until after you play it to so you can fish for a buffed unit. Spirit Fire and Dunekeeper are primarily for stall -- Spirit Fire in particular can bail you out of a lot of desperate situations, so don't be afraid to burn a turn just to bank mana to cast it early. 2x Rite of Negation just "feels right", but if you're short on epic wildcards and/or just planning on grinding AI who won't give you many opportunities to use it feel free to substitute.
