Whenever this creature enters or attacks, discard a card, then seek a nonland card. When you discard a card this way, this creature deals damage equal to the discarded card's mana value to any target.

When you set this scheme in motion, look at the top four cards of your library and separate them into a face-down pile and a face-up pile. An opponent chooses one of those piles. Put the cards in that pile into your hand and the rest on the bottom of your library in any order.

Choose one —
• Two-Weapon Fighting — Double target creature's power and toughness until end of turn.
• Archery — This spell deals 5 damage to target creature with flying.
