These lands feature all four of the Turtles on their way to protect the city from villains (or maybe they're on their way to pick up a pizza)
Astral starts having one when he realizes Kaito's dueling outdoes his own in every aspect, and quietly just begins to clam up, while Yuma loses it in front of Kotori, screaming about how he can never achieve his goals with his own weakness
When it comes to disappointment, the regret from losing a card to dusting is the same as regretting a trade you made
The first ability not only helps to fuel the second but gives you instant-speed protection for important artifacts
Rather than being a Main Deck monster, these go face-down in your Extra Deck at the start of your duel, and you then first have to Xyz Summon them to get them out, then like other Pendulum Monsters, if they destroyed or sent to the Graveyard, they go face-up in the Extra Deck
Hopefully you have a solid grasp of what differentiates these two styles and which best suits your collection
