your opponent cannot target it with card effects this turn
This is taking that mission one step further, where now you need to collect, specifically, the 2-star rainbow edge versions of Articuno EX, Zapdos EX, and Moltres EX
We also needed something for chocobos to do, and the saddle mechanic didn't exist yet due to the development timelines of Outlaws of Thunder Junction and Aetherdrift
So rather than catalogue every card, Ill explain the different categories of money cards, their approximate range of values, why they are valuable, and how likely you are to stumble across some in your collection
If you spot Lost Origin, Silver Tempest, or Crown Zenith, grab them
