Here are the latest card rebalances and breakdowns for the Alchemy format, releasing April 4, 2023.

Ninjas

The changes around Kamigawa: Neon Dynasty's Ninjas aim to improve their defensive capabilities. The buffs are primarily focused on adding more 4-toughness Ninjas and decreasing ninjutsu costs.

With lower ninjutsu costs, players have more available mana to cast interactive spells and creatures to block with in the same turn they use ninjutsu. The lower ninjutsu costs and other general buffs to the deck also better reward players for enabling ninjutsu and building around the mechanic.

Defensive Tools

These buffs aim to improve tools that help counter aggressive decks such as Mono-Red. Increasing toughness to 4 on creatures and increasing the life gain on cards better matches them against Lightning Strike and helps decks reach the late game against aggressive decks.

Knockout Blow's rebalance is intended to buff it in main decks by allowing it to destroy cards like Sheoldred, the Apocalypse; Raffine, Scheming Seer; and Thundering Raiju.
