The 5 Card Combo: Ruby Dragon +
Parallel Universe x 2 +
Obsidian Dragon +
Sky Blitz = 114 Damage.
Support Cards:Supernova: Necessary to boost your quanta to play your combo.
Sundial: Excellent stalling against rush and domin decks, with the added bonus of drawing through your deck to reach your combo. Unupgraded so it won't harm your opening draw.
Precognition: Mostly drawpower, but can be useful to see your opponents hand so you know when it would be best to play your Silence. Make sure you will have enough Time quanta remaining to keep your sundial chain intact.
Shard of Bravery: Excellent added drawpower, especially when your Sundials and Silence can mitigate the advantage your opponent will get.
Silence: A great technical card, allowing you to protect yourself from various counters, including finding a hole in a Dim Shield chain. Make sure you will have enough Aether quanta remaining to play your Parallel Universes. Also, against various decks you can lay down 50 damage and use a Silence to win in 2 turns, in a pinch.
