Like most Pokmon cards, the value of Rayquaza-EX depends on a few consistent factors: its rarity, the printing and finish (regular or foil), its physical condition, and the set it was printed in (XY Black Star Promos)
Ultra Shiny is an even rarer version, and unlike the Shiny version, instead of stars appear squares with a directed animation when the Pokmon goes into battle
Pidgeot's ability, Drive Off, allows you to send your opponent's active Pokemon back to their bench
3 Latias EX: Dragon (Ultra Rare) $115.65 The Flying Focal Point As one of the most expensive sets in the EX era, Dragon is home to an incredible collection of Pokemon that matches the set's titular theme
Cycle of Evoke Rares Solitude Subtlety Grief Fury Endurance Personally, I think the green and white Evoke rares are the strongest in this cycle
Also exiling is the preferred method of removal for casual formats like Commander since it gets past indestructible things like Darksteel Plate, tricks like Heroic Intervention, and it permanently ends their threat, and they cannot be recurred
