Card Rulings

If Niko Aris enters the battlefield without being cast, they were cast for a cost other than their mana cost, or if X was chosen to be 0, the enters-the-battlefield ability won't create any Shard tokens.

Niko deals all the damage for their second ability at the same time. For example, if you've drawn two cards this turn, Niko will deal 4 damage to the target tapped creature; they won't deal 2 damage, then deal 2 more damage.

Shard is a new predefined token, similar to Food and Treasure. A Shard token is a colorless enchantment with " , Sacrifice this enchantment: Scry 1, then draw a card." Shard is a new enchantment subtype.

The delayed triggered ability created by Niko's first loyalty ability will trigger whenever the target creature deals any damage that turn, not just combat damage.
