Asgore's Truck was added in Beta 39.0.
Similar to Flower Can, one of these give you 2 Green Flowers, making this already very effective in a Plant deck. And even though Truck adds the Flowers to your hand with Magic instead of directly summoning them with Dust like Flower Can does, they are 0G monsters, so you don't have to think about money. Instead, avoid using this while having a full hand before playing it, otherwise you miss out on a Flower.
Alongside this effect, it also has Haste to be able to attack a monster right away with its 3 ATK, making it somewhat similar to Snailmobile. Truck also costs 1 less from Snailmobile and 1 more from Flower Can, at 4G. But it only has 1 HP, so it most likely dies after attacking.
