Nylea, Keen-Eyed

Lifelink When this creature enters, search your library for a card, put it into your graveyard, then shuffle. Spells you cast from your graveyard cost 1 less to cast.

When Kroxa enters, sacrifice it unless it escaped. Whenever Kroxa enters or attacks, each opponent discards a card, then each opponent who didn't discard a nonland card this way loses 3 life. Escape—BBRR, Exile five other cards from your graveyard. (You may cast this card from your graveyard for its escape cost.)

Menace When Atris enters, target opponent looks at the top three cards of your library and separates them into a face-down pile and a face-up pile. Put one pile into your hand and the other into your graveyard.

Choose one — • Search your library for up to X land cards, reveal them, put them into your hand, then shuffle. • Nylea's Intervention deals twice X damage to each creature with flying.

+1: Create a 2/3 blue and black Nightmare creature token with "Whenever this token attacks or blocks, each opponent exiles the top two cards of their library." −3: Return target nonland permanent to its owner's hand, then that player exiles a card from their hand. −7: You may cast up to three spells from among face-up cards your opponents own from exile without paying their mana costs.

Indestructible As long as your devotion to red is less than five, Purphoros isn't a creature. Other creatures you control have haste. 2R: You may put a red creature card or an artifact creature card from your hand onto the battlefield. Sacrifice it at the beginning of the next end step.

Haktos attacks each combat if able. As Haktos enters, choose 2, 3, or 4 at random. Haktos has protection from each mana value other than the chosen number.

GW: This creature gains indestructible until end of turn. When this creature dies, return it to the battlefield. It's an Aura enchantment with enchant creature you control and "GW: Enchanted creature gains indestructible until end of turn," and it loses all other abilities.
