Toriel's Car is the main card of the revamped Turbo Decks, providing both cost reduction and the ability to have an endless deck, similar to Future decks.
Just by summoning 2 Cars, the former will use its passive effect to copy the latter to your deck. With a 3rd Car, both the 1st and 2nd will copy the 3rd, giving 2 copies at once.
Filling your deck with Turbo monsters will make it so that whenever you draw a Car, each of them in your hand will get their cost reduced by 1. After some time, when you have copied many Cars, this can happen very often.
Due to Car's cost of 5G, Prosperity is a good Artifact to use with it. As whenever you summon one, you restore 1 HP. However, keep in mind that drawing a Car will reduce the cost of other Cars in your hand. And with a cost of 4G, Prosperity won't activate.
