chinese pokemon booster box TCG Sun & Moon All Stars Collection Violet era with the launch of the Collect 151 Journey Pokemon China: CBB3C: Gem Pack

15 Mana

It ported over to the UW Humans and Bant Company decks of Shadows over Innistrad Standard, and even broke into Modern for a time (back when Celestial Collonade and Vendilion Clique were the bread and butter of the deck)

Some cards in Future Sight wouldn't appear again in regular expansion sets for years or even a decade

Each colour is associated with a strategy: Steel hits hard, Sapphire is slow and strategic, Ruby hits fast but weak, Emerald is about thinking beyond the playing field, Amythest nerfs your opponent and Amber heals and buffs your deck

It can either speed up or slow down anything with time counters, and being an instant means you can do it at the most disruptive moment
