Theros Beyond Death

Alirios, Enraptured | Legendary Creature | Human | Alirios, Enraptured enters the battlefield tapped. Alirios doesn't untap during your untap step if you control a Reflection. When Alirios enters the battlefield, create a 3/2 blue Reflection creature token. | Kieran Yanner

Callaphe, Beloved of the Sea | Legendary Enchantment Creature | Demigod | Callaphe's power is equal to your devotion to blue. (Each {U} in the mana costs of permanents you control counts toward your devotion to blue.) Creatures and enchantments you control have "Spells your opponents cast that target this permanent cost {1} more to cast." | Zack Stella

Whirlwind Denial | Instant | | For each spell and ability your opponents control, counter it unless its controller pays {4}. | Lie Setiawan

Eutropia the Twice-Favored | Legendary Creature | Human Wizard | Constellation — Whenever an enchantment enters the battlefield under your control, put a +1/+1 counter on target creature. That creature gains flying until end of turn. | Sara Winters
