Springans and Time Thiefs Synergy:
On a surface level, Springans don't need a normal summon and Time Thiefs brings a powerful normal summon, Time Thief Regulator, a archetypal Rescue Rabbit to the board. Additionally, Springans' core field spell, Great Sand Sea- Gold Golganda, prevents OTK when Time Thief Redoer is threatened.
Taking a closer look at the individual cards, Time Thief Bezel Ship and Time Thief Winder find easy materials to detach from the shared effects of all Springans monster to attach themselves to their archetypal XYZs while Time Thief Chronocorder is happy to trigger itself off Merrymaker and sit under the protection of Gold Golganda. Springans brings the firepower to the table with the unique board destruction effect of Exblower, and enables 4 materials Zeus.
Cards Choices and Ratio Explanation:
2 Branga: Springans sucks to draw in multiples and level 8 Springans are even more useless when you are cutoff from the field spell. There are 3 major targets to consider when searching, Springans Rockey, Springans Watch, and Springans Blast. Springans Blast is the one you should consider the most, but Merrymaker's effect to send Sprind, the Iron Dragon effect for a follow up is powerful too.
2 Great Sand Sea - Gold Golgonda : While central to the Springans Strategy, with Pot of Prosperity, Springans Watch and Springans Booty, it is easy to find a copy of the field spell. What you don't want to find is the second copy of Gold Golgonda. It is a dead card that you can not even discard to summon a Springans XYZs.
2 Time Thief Winder - Brings the total target of Time Thief Regulator's target to 4, and is a body that can special summon itself.
1 Time Thief Flyback - The most questionable choice in the list, It finds the missing Chronocorder or Bezel Ship when you make Time Thief Redoer and attaches Time Thief Retrograde from deck when you make Redoer without Regulator.
1 Springans Blast - Worst Discard for Gold Golganda and might brick.
2 The Phantom Knight of Shade Brigandine - Free Level 4 body that enables Redoer. It bricks at 3 :)
Drill Driver Vespenato - DO NOT BANISH this off prosperity, it removes Merrymaker from the board so you can summon the Exblower.
Sprind the Irondash Dragon - Merrymaker can foolish this to grave, and is essentially a +2 when you summon Rockey and add back the Brothers in grave.
Dingirsu, the Orcust of Evening Star - It is possible to make rank 8 in this deck, but it doesn't come up alot, don't hesitate to banish this for prosperity if you don't think you can make it. I like Ding because it outs indestructible cards.
Time Thief Perpetua - Reborns Time Thief Redoer, and help attaches Flyback for removal or a monster when using Zeus.
Gameplay( What I usually do) :
1: Make Merrymaker and Redoer, depending on the hand, you can choose to summon Captain Sargus for a pop, or make a abyss dweller. Evaluate your hand and see if you have any follow-up.
2. Survive, You usually have a spell negate, a attack negate, and the odd handtrap.
3. Make Exblower and start blasting. Maybe make a Zeus, search Springans Blast and make any Rank4.
