Upgrade sequence of 2022 pickup hammer card set

The first echelon: siege hammer-small lightning-electric method-poison; The second echelon: assassin-ranger; The third echelon: big pickup truck-ghost. The card types of the first echelon include rare cards, ordinary cards, legendary cards and epic cards, and each type of card covers one card. This consideration can well avoid the problem of having to consider too many legendary cards at the same time. But the card level of the second and third echelon is not completely critical. For example, the ranger and the electric method sometimes need one of the deception spells, and the height of the ranger is also killed by a fireball, so as to maximize the benefits.
