In the tournament scene, Champions of Kamigawa contributed with a large number of finishers, like Kokusho, the Evening Star, Keiga, the Tide Star, Yosei, the Morning Star and Meloku the Clouded Mirror. It also provided excellent green mana fixing, like Sakura-Tribe Elder and Kodama's Reach, and an arsenal of cards that fueled multiple colored control decks, such as Gifts Ungiven. A notable sideboard card was also found in Cranial Extraction.
- Time Stop — Rules had to be added to the Comprehensive Rules for ending the turn thanks to this card.
- Sensei's Divining Top — A card which saw widespread tournament play due to the ability of setting up advantageous draws repeatedly and functioning as an emergency card-draw. The card was later banned in Extended and Modern, not due to power concerns but because the card tended to slow the game down immensely and was thus detrimental to tournament play. It is also a key piece in the a lock with Counterbalance (printed later in Coldsnap) due to its ability to change the card Counterbalance would reveal at instant-speed. Divining Top could also place itself on top of the library, making any spell with converted mana cost of 1 impossible to resolve.
