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

Draw three cards.

The owner of target permanent shuffles it into their library, then reveals the top card of their library. If it's a permanent card, they put it onto the battlefield.

This spell can't be countered. Counter target spell you don't control. Overload {1}{U}{U}{R} (You may cast this spell for its overload cost. If you do, change "target" in its text to "each.")

Lightning Bolt deals 3 damage to any target.

Defender Whenever you cast an instant or sorcery spell, this creature deals 1 damage to each opponent.

If this card is in your opening hand, you may begin the game with it on the battlefield. You may cast spells as though they had flash.

Cumulative upkeep {1} (At the beginning of your upkeep, put an age counter on this permanent, then sacrifice it unless you pay its upkeep cost for each age counter on it.) Whenever an opponent casts a noncreature spell, you may draw a card unless that player pays {4}.

Banefire deals X damage to any target. If X is 5 or more, this spell can't be countered and the damage can't be prevented.

This spell costs {1} less to cast for each creature on the battlefield. Blasphemous Act deals 13 damage to each creature.

Exile X target creatures. For each creature exiled this way, its controller creates a 2/2 green Boar creature token.

({U/P} can be paid with either {U} or 2 life.) Look at target player's hand. Draw a card.

Return target instant or sorcery card from your graveyard to your hand. Flashback {2}{R} (You may cast this card from your graveyard for its flashback cost. Then exile it.)

Each instant and sorcery card in your graveyard gains flashback until end of turn. The flashback cost is equal to its mana cost. Flashback {4}{R} (You may cast this card from your graveyard for its flashback cost. Then exile it.)

Look at the top three cards of your library, then put them back in any order. You may shuffle. Draw a card.
