Daxos's Torment
Enchantment
Constellation — Whenever this enchantment or another enchantment you control enters, this enchantment becomes a 5/5 Demon creature with flying and haste in addition to its other types until end of turn.
The terrors of the Underworld travel alongside those who return to the mortal realm.

Although Daxos’s Torment will become a creature after it enters the battlefield, it doesn’t enter as a creature. Abilities that trigger whenever a creature enters the battlefield won’t trigger.

If the triggered ability resolves while Daxos’s Torment is already a creature, that ability will override any effects that set its power or toughness to a specific value. Effects that modify power or toughness without directly setting them to a specific value will continue to apply.
