Whenever you cast a noncreature spell, create a Vial token. (It's an artifact with “{1}, Sacrifice this and another permanent: Draw a card. Activate only during your turn.”)

Draw a card for each creature you control.
Agonize (You may cast this card from your graveyard by putting a -1/-1 counter on a creature you control in addition to paying its other costs. Then exile this card.)

Any number of target players mill twice X cards, where X is the number of artifacts and enchantments you control. Then you may cast a nonland card with mana value X or less from a graveyard without paying its mana cost. You can't cast more spells this turn.

Enchant creature
Enchanted creature loses all abilities and is a blue Wizard creature with base power and toughness 1/1.

Each player shuffles their hand and graveyard into their library. Then each player draws seven cards. If you didn't control a blue legendary creature or planeswalker as you cast this spell, discard three cards. Exile Entelan Erasure.

Return any number of target nonland permanents with different mana values to their owners' hands. If seven or more permanents were returned this way, you may cast spells without paying their mana costs until end of turn.

Enchant creature
You control enchanted creature.
Enchanted creature gets +1/+1 and has slipstream. (This creature can't be blocked as long as only creatures with slipstream are attacking.)

Choose X. You may choose the same mode more than once.

Vanishing 2 (This permanent enters with two time counters on it. At the beginning of your upkeep, remove a time counter from it. When the last is removed, sacrifice it.)
