Oath of Nissa

Timeline
Rationale
In Pioneer, *Oath of Nissa* was initially banned to mitigate the excessive consistency and synergy it provided, particularly within green ramp decks. Its removal was enacted because the card was deemed to contribute to problematic strategies and exacerbate unhealthy play patterns by supporting archetypes that utilized multiple three-mana planeswalkers. Following this ban, the card was later unbanned in the Pioneer format to restore power to key strategies, such as those revolving around *Nykthos, Shrine to Nyx* ramp decks.
