You don't lose the game for drawing from an empty library.
As long as you have seven or fewer cards in each of your libraries, you may cast spells without paying their mana costs.

Flash (You may cast this spell any time you could cast an instant.)
You may cast Wizard spells as though they had flash.
{U}{U}, Tap two untapped Wizards you control: Copy target instant or sorcery spell. You may choose new targets for the copies.

When Lotus Debutante enters, create a colorless artifact token named Lotus Petal with “{T}, Sacrifice this artifact: Add one mana of any color.”
{3}{U}: Draw a card.

Distorted (This creature can be blocked by tapped creatures but not untapped creatures.)
{1}{U}, Discard Lusterwing Owl: Return target enchantment to its owner's hand.

{X}, {T}: Target player mills X cards.

Instant and sorcery spells you cast cost {1} less to cast.
{U}, {T}, Exile three instant and/or sorcery cards from your graveyard: Draw a card.

You may choose not to untap Master of Minds during your untap step.
{T}: Gain control of target creature with mana value X or less for as long as Master of Minds remains tapped, where X is the number of Islands you control.

When Master of the Abyss enters, draw two cards, then discard a card.
{2}{U}{U}, {T}, Discard two cards: Create an X/X black Horror creature token, where X is the number of cards in your graveyard.

When Minister of Madness enters, create a 0/1 blue Weird creature token with flying.
{2}{U}, Sacrifice a creature: Search your library for an instant or sorcery card with mana value equal to 1 plus the sacrificed creature's mana value, exile that card, then shuffle. Then you may cast that card without paying its mana cost. Activate only as a sorcery.

{2}{U}, Remove a counter from a permanent you control: If it was a +1/+1 counter, draw a card. If it was a lore counter, put a +1/+1 counter on Minnow's Accomplice. Activate only as a sorcery.

Whenever you cast your second spell each turn, audition for blue. (Create a 1/1 Construct Actor creature token, a Wizard Role giving 2/2 and prowess, or a Warlock Role giving 2/1 and flying. Roles replace older ones.)

When Oracle of Edicts enters, adjudicate. (Create a white Aura enchantment token with enchant creature and “Sacrifice this token: Untap enchanted creature” attached to target creature.)
Whenever an Aura you control enters, scry 1.

Each instant and sorcery card in your hand has cycling {2}. ({2}, Discard this card: Draw a card.)
At the beginning of your end step, if there are four or more instant and/or sorcery cards in your graveyard, you may pay {1}{U/R}. If you do, return an instant or sorcery card at random from your graveyard to your hand.

Whenever you cast a noncreature spell, up to one target artifact or non-Aura enchantment you control becomes a 3/3 creature in addition to its other types until end of turn.

When Pilgrim of Many Provinces enters, draw a card. Then you may discard a creature card. If you do, draw a card.

When Posthumous Informant dies, investigate. (Create a colorless Clue artifact token with “{2}, Sacrifice this artifact: Draw a card.”)

When Prodigious Telemancer enters, you may draw a card, then discard a card.
Whenever you cast an instant or sorcery spell, you may aetherize target creature you control. (To aetherize, create a token that's a copy of it, then exile that token.)

Renown 1 (When this creature deals combat damage to a player, if it isn't renowned, put a +1/+1 counter on it and it becomes renowned.)
Rafter Stalker can't be blocked by creatures with greater power.

Hexproof
Paranoia {1}{U} (You may cast this spell for its paranoia cost when a permanent you control leaves the battlefield.)

Flying
{2}{U}: Switch target creature's power and toughness until end of turn.

When Rhudai Overseer enters, look at the top four cards of your library. You may reveal an artifact or enchantment card from among them and put it into your hand. Put the rest on the bottom of your library in any order.
