Calix, Guided by Fate [March of the Machine: The Aftermath]

Constellation—Whenever Calix, Guided by Fate or another enchantment enters the battlefield under your control, put a +1/+1 counter on target creature.

Whenever Calix or an enchanted creature you control deals combat damage to a player, you may create a token that's a copy of a nonlegendary enchantment you control. Do this only once each turn.
