MTG Izzet Midrange Deck by HardSci

Whenever you discard one or more cards, put that many +1/+1 counters on this creature. Cycling {2} ({2}, Discard this card: Draw a card.)

When this creature enters, discard a card, then draw a card. Delirium — Whenever this creature attacks for the first time each turn, if there are four or more card types among cards in your graveyard, untap target creature. After this phase, there is an additional combat phase.

Haste When Tersa Lightshatter enters, discard up to two cards, then draw that many cards. Whenever Tersa Lightshatter attacks, if there are seven or more cards in your graveyard, exile a card at random from your graveyard. You may play that card this turn.

Backup 2 (When this creature enters, put two +1/+1 counters on target creature. If that's another creature, it gains the following ability until end of turn.) {1}, Sacrifice this creature: It deals damage equal to its power to any target.

{0}: Add X mana in any combination of {U} and/or {R}, where X is Vivi Ornitier's power. Activate only during your turn and only once each turn. Whenever you cast a noncreature spell, put a +1/+1 counter on Vivi Ornitier and it deals 1 damage to each opponent.

Flying When this creature enters, draw a card. As long as you have one or fewer cards in hand, if you would draw one or more cards, you draw that many cards plus one instead. Warp {1}{U}

You may spend mana as though it were mana of any color to activate abilities of creatures you control. Creatures you control with +1/+1 counters on them have all activated abilities of all creature cards exiled with Agatha's Soul Cauldron. {T}: Exile target card from a graveyard. When a creature card is exiled this way, put a +1/+1 counter on target creature you control.

When Proft's Eidetic Memory enters, draw a card. You have no maximum hand size. At the beginning of combat on your turn, if you've drawn more than one card this turn, put X +1/+1 counters on target creature you control, where X is the number of cards you've drawn this turn minus one.

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.

Bargain (You may sacrifice an artifact, enchantment, or token as you cast this spell.) Torch the Tower deals 2 damage to target creature or planeswalker. If this spell was bargained, instead it deals 3 damage to that permanent and you scry 1. If a permanent dealt damage by Torch the Tower would die this turn, exile it instead.

Draw three cards. Then discard two cards unless you discard a creature card. Harmonize {4}{U} (You may cast this card from your graveyard for its harmonize cost. You may tap a creature you control to reduce that cost by {X}, where X is its power. Then exile this spell.)

({T}: Add {U}.)

{T}: Add {U}. Channel — {3}{U}, Discard this card: Return target artifact, creature, enchantment, or planeswalker to its owner's hand. This ability costs {1} less to activate for each legendary creature you control.

({T}: Add {R}.)

{T}: Add {R}. Channel — {3}{R}, Discard this card: Create two 1/1 colorless Spirit creature tokens. They gain haste until end of turn. This ability costs {1} less to activate for each legendary creature you control.

{T}: Add {R}. {T}: Add {U}. Activate only if you control an Island or a Mountain.

This land enters tapped unless you control two or fewer other lands. {T}: Add {U} or {R}.

{T}: Add {C}. {1}: This land becomes a 2/2 creature with all creature types until end of turn. It's still a land.
