Please Bann Cyclonic Rift. it is the most unfair, salty one sided boardwhipe in the game. It is instant speed and it is one sided. Almost all other one sided boardwhipes are sorcery speed and affect all players. all other boardwhipes are conditional. they have downsides. In white, they affect all players, or only affects creatures that are attacking and gives the opponent lands in compensation... or you need to choose a creature type, or are sorcery speed like Kindred dominance, plus you need to select a creature type... CR not only does not have a downside, but affects ALL permanents that ALL opponents control!!!! this is really a broken card. It NEEDS to be banned in Arena. It is particularly devastating in 1vs1.
