It's not very hard to grasp the strategy - if you play it right, you'll have 100 damage in one turn with nothing to stop you. This deck has three basic parts: Speed drawing, minor control, and the final smash itself. Some of these cards can be swapped out of course.
Once you get out an Hourglass, you draw as quickly as you can. The BBs, Fire Storm, and Sancs can be used for basic control. Once you're hand has 4x Shard of Freedom, 1x Ball Lightning, 1x Fractal, and 1 Sky Blitz. The second version of this deck - which I have in a spoiler below - was made long before the new generations of shards, and used chimera.
The downside of not having chimera is you can't use your BBs on BLs against creature less/immortal creature decks. There's drawing to 8 cards and discarding for that, however. Know thine enemy.
Weaknesses:100+ HP Stalls - This deck is made for 100 HP only. Any more and you have to be tricky with BBs and sparks to win
Fastest Rushes - Can possibly kill you before you get set up
Permanent Control - Not because of the SoFres getting destroyed, as you hold them in your hand, but because of hourglasses. Can be circumvented by having Protect Artifact.
Other Ideas:Supernovas: In before I get more people saying this needs supernovas. No, no, and more no. Especially not after the singularity addition.
Sundials, Phase Shields, Wings: These provide a good bit of stall when chained. However, Sundial will probably need to replace hourglasses, making you slower, and the latter two require heavy quanta of elements already used in the deck.
Purify, Plague, [insert cheap utility here]: These are definitely nice. My original deck had Explosion and Purify, however I ditched these for Chimera and Sanctuary. Shields as well would be a good addition, especially Dusk or Permafrost.
Unupped Versions: Maybe so, probably not. Everything is more expensive, while Balls, Towers, and Hourglasses at the very least have to be upgraded.
