What it does
Constellation is a triggered ability found on Theros: Beyond Death cards. Whenever an enchantment enters the battlefield under your control, each of your permanents with constellation triggers. The effect varies—drawing cards, gaining life, draining opponents, growing creatures, and so on.
The most common misconception is what counts as the trigger. Constellation cares about any enchantment you control entering—not just other enchantments. That includes the constellation permanent itself when it enters (if it's an enchantment), enchantment creatures, Sagas, Auras, and even God cards. It triggers once per enchantment entering, so multiple constellation permanents each trigger separately. Note it only watches your permanents entering, not opponents'.
In Commander, constellation shines in enchantment-heavy builds (often green/white or black). With cheap or token-generating enchantments, you can chain multiple triggers per turn, snowballing card advantage or incremental drain quickly.
