MTG Dimir Midrange Deck by Seibo

Flying When this creature enters, create a Map token. (It's an artifact with "{1}, {T}, Sacrifice this token: Target creature you control explores. Activate only as a sorcery.")

Flash Vigilance When this creature enters, tap target creature an opponent controls and put a stun counter on it. {1}{U}, {T}: Shuffle this creature and target creature with a stun counter on it into their owners' libraries.

Menace Ward—Discard a card. Whenever this creature attacks, put a +1/+1 counter on target creature an opponent controls.

Flash When this creature enters, counter up to one target activated or triggered ability. If an ability of an artifact, creature, or planeswalker is countered this way, that permanent loses all abilities for as long as this creature remains on the battlefield. (Mana abilities can't be targeted.)

Deathtouch Whenever this creature attacks the player with the most life or tied for most life, create a 1/1 white Vampire creature token with lifelink. Whenever this creature attacks while you have the most life or are tied for most life, you draw a card and you lose 1 life.

Flash Whenever a creature you control deals combat damage to a player, draw a card. When Enduring Curiosity dies, if it was a creature, return it to the battlefield under its owner's control. It's an enchantment. (It's not a creature.)

Flash When this enchantment enters, target creature an opponent controls gets -3/-3 until end of turn. Creatures your opponents control can be the targets of spells and abilities as though they didn't have hexproof. Ward abilities of those creatures don't trigger.

Spree (Choose one or more additional costs.) + {3} — Create a 2/2 white Spirit creature token with flying. + {1} — Counter target spell unless its controller pays {2}.

As an additional cost to cast this spell, discard a card or pay 3 life. Destroy target creature or planeswalker.

Destroy target non-outlaw creature. (Assassins, Mercenaries, Pirates, Rogues, and Warlocks are outlaws. Everyone else is fair game.)

Target opponent reveals their hand. You choose a noncreature, nonland card from it. That player discards that card.

Target creature gets -2/-2 until end of turn. Void — That creature gets -10/-10 until end of turn instead if a nonland permanent left the battlefield this turn or a spell was warped this turn.

Ninjutsu {1}{U}{B} ({1}{U}{B}, Return an unblocked attacker you control to hand: Put this card onto the battlefield from your hand tapped and attacking.) During your turn, as long as Kaito has one or more loyalty counters on him, he's a 3/4 Ninja creature and has hexproof. +1: You get an emblem with "Ninjas you control get +1/+1." 0: Surveil 2. Then draw a card for each opponent who lost life this turn. −2: Tap target creature. Put two stun counters on it.

({T}: Add {U}.)

({T}: Add {B}.)

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

This land enters tapped. {T}: Add {U} or {B}. {2}{U}{B}: Until end of turn, this land becomes a 4/4 blue and black Shark creature with deathtouch. It's still a land. Whenever this land attacks, target player mills four cards.

({T}: Add {U} or {B}.) As this land enters, you may pay 2 life. If you don't, it enters tapped.

{T}: Add {C}. {4}: This land becomes a 3/3 creature with vigilance and all creature types. It's still a land.

This land enters tapped unless it's your first, second, or third turn of the game. {T}: Add {C}. {T}, Pay 1 life: Add one mana of any color.
