Echo, Perceptive Prodigy

Flash When this enchantment enters, target creature an opponent controls gets -3/-3 until end of turn. Creatures your opponents control can be the targets of spells and abilities as though they didn't have hexproof. Ward abilities of those creatures don't trigger.

When this creature enters, you may search your library for a basic land card, put it onto the battlefield tapped, then shuffle.

T: Add three mana of any one color.

Lightning Bolt deals 3 damage to any target.

When this creature enters, you may search your library for a Food card, reveal it, put it into your hand, then shuffle. If you don't put a card into your hand this way, create a Food token. (It's an artifact with "2, T, Sacrifice this token: You gain 3 life.")

When this artifact enters, it deals 4 damage to any target and 3 damage to you. 2, T, Sacrifice this artifact: You gain 3 life.

Gift a tapped Fish (You may promise an opponent a gift as you cast this spell. If you do, they create a tapped 1/1 blue Fish creature token before its other effects.) Return target creature an opponent controls to its owner's hand. If the gift was promised, instead return target nonland permanent an opponent controls to its owner's hand.

T: Add C. 3, T: Target creature with power 3 or less can't be blocked this turn.
