Anyway, this arena is actually a pretty good lesson on how to construct a deck in this game
In Japanese sets, a gold-on-black card like this Charizard is classified as a Mega Ultra Rare, essentially the highest rarity of the set
The card's powerful effects can reduce enemy monsters' attack points to zero or send Speedroid monsters to the graveyard to summon the card from the Pendulum Zone
Not only that, but the Lapras ex card specifically is not available in any of the current "Genetic Apex" packs, so for the time being the chance to earn a Lapras ex is over (though the eventual addition of the Pokemon TCG Pocket trading feature means that you might be able to swap them into you deck by getting them from another player)
You can see how the Cobra 800A Jump Starter performed in each category below: The lithium-cobalt battery has USB-C and USB-A ports to keep your phone and other electronics charging on long trips
Elemental Hero Chaos Neos may not be the most practical Monster to bring out, but seeing as the Ghost Rare version of the card is so valuable, you might want to flex it just for fun
