This deck is a fragile but powerful combo deck that spends its early turns developing its board with Mana Vaults, Sylvan Library and Howling Mine. The plan after that involves getting a Time Vault on the table and as that card is restricted the deck usually plays a couple of Transmute Artifact. When the Time Vault is in play the deck starts to go off by untapping the Time Vault using Twiddle.
Each Twiddle becomes a one mana Time Walk and thanks to Howling Mines and Sylvan Library you usually end up drawing another Twiddle, Regrowth, Recall or actual Time Walk to continue taking turns. While taking all of the turns you also slowly build up your mana to be able to cast a big enough Fireball to end your opponent.
To make the kill a little easier the deck often utilizes Mirror Universe and Sylvan Library to give the opponent a lower life total to Fireball away.
