Thematically, youre building up the story of another character, taking a lowly Llanowar Elf up to a massive 10/10 creature, and now you can tell their exploits throughout time (or at least until you win the battle)
However, a card like Lapras takes advantage of the already-present Water Energy in the deck
Charizards high-risk, high-reward nature is further underscored by the updated Mega Evolution rule: if a Mega EX is KOd, your opponent takes 3 Prize cards instead of 2 a built-in balance to its power
Those three cards represent the higher end of whats featured in this drop, too
I am running a pair of Soul Sisters that have 2 power since they are key forms of life gain here
I'm sure there are more but now you can at least talk to all the npcs without crashing, which hey that's a step forward
