Magecraft — Whenever you cast or copy an instant or sorcery spell, draw a card.

Whenever you cast a creature spell, draw a card.

Draw three cards, then put two cards from your hand on top of your library in any order.

Whenever this creature attacks, scry 1. Whenever you scry, tap up to X target nonland permanents, where X is the number of cards looked at while scrying this way.

At the beginning of your upkeep, scry 1. Whenever you cast a creature spell, you may pay {G}. If you do, draw a card.

Whenever you cast your first spell each turn, reveal the top card of your library. You may cast it without paying its mana cost if it's a spell with lesser mana value. If you don't cast it, put it into your hand.

If you would draw a card, draw two cards instead.

{2}, {T}: You gain 5 life. Shuffle this artifact and your graveyard into their owner's library.

Choose two — • Return target creature or planeswalker to its owner's hand. • Counter target artifact or enchantment spell. • Put two +1/+1 counters on target creature. • Target player shuffles up to three target cards from their graveyard into their library.

This creature enters with four -1/-1 counters on it. {G/U}: This creature gains shroud until end of turn. (It can't be the target of spells or abilities.) Whenever you cast a green spell, remove a -1/-1 counter from this creature. Whenever you cast a blue spell, remove a -1/-1 counter from this creature.

Flying Prowess (Whenever you cast a noncreature spell, this creature gets +1/+1 until end of turn.) Whenever you cast an instant or sorcery spell, tap target creature an opponent controls. That creature doesn't untap during its controller's next untap step.

When this creature enters, you may destroy target artifact or enchantment.

Flying Whenever this creature deals combat damage to a player, you may destroy target artifact or enchantment that player controls.

When this creature enters, you may exile an instant card from your hand. {X}, {T}: Copy the exiled card. You may cast the copy without paying its mana cost. X is the mana value of the exiled card.

Imprint — When this artifact enters, you may exile an instant card with mana value 2 or less from your hand. {2}, {T}: You may copy the exiled card. If you do, you may cast the copy without paying its mana cost.

Morph {4}{U}{U} (You may cast this card face down as a 2/2 creature for {3}. Turn it face up any time for its morph cost.) When this creature is turned face up, counter target spell. If that spell is countered this way, exile it instead of putting it into its owner's graveyard. You may cast that card without paying its mana cost for as long as it remains exiled.
