You choose from it a nonland card with mana value 3 or less and a card with mana value 4 or greater. That player discards those cards.

Whenever this creature blocks or becomes blocked by a creature, this creature deals 3 damage to that creature and 3 damage to that creature's controller.

Whenever a creature you control with toughness 4 or greater dies, draw a card.

You may cast this card from exile. When this creature becomes the target of a spell or ability an opponent controls, exile this creature.

Escalate 1 (Pay this cost for each mode chosen beyond the first.) Choose one or more — • Target player discards all the cards in their hand, then draws that many cards. • Collective Defiance deals 4 damage to target creature. • Collective Defiance deals 3 damage to target opponent or planeswalker.

First strike When this creature enters, you may search your library for a legendary card, reveal it, put it into your hand, then shuffle.

This creature can't attack or block unless a player has no cards in hand.

Flying Whenever a player casts an instant or sorcery spell that targets only this creature, that player copies that spell for each other creature they control that the spell could target. Each copy targets a different one of those creatures.
