Whenever you cast a spell, if you cast it for an alternative cost or cast it from anywhere other than your hand, create two 1/1 blue Elemental creature tokens with flying. (Reconstruct and rhapsody are alternative costs, hybrid costs are not.)

Flying
Crew 4 (Tap any number of creatures you control with total power 4 or greater: This Vehicle becomes an artifact creature until end of turn.)
Tap two untapped other artifacts you control: Encampment Blimp becomes an artifact creature until end of turn. Scry 1.

Destroy all nonenchantment permanents. If thirty or more lands were destroyed this way, you win the game.

Artifact creatures you control have haste.
At the beginning of your upkeep, create a 1/1 colorless Construct artifact creature token. If you control six or more artifacts, create a 6/6 colorless Golem artifact creature token instead. Tokens created this way attack this turn if able.

Converge — Each creature gets -X/-X until end of turn, where X is the number of colors of mana spent to cast Enjoy the Silence.

Flying
Augmented — Whenever you cast a spell, if you've spent {W}{U}{B}{R}{G} to cast spells this turn, put a +1/+1 counter on Enlightened Guardian. It loses this ability and gains “Whenever this creature attacks, draw two cards.”

Double strike
Experience (Whenever this creature attacks, if it has fewer than three +1/+1 counters on it, put a +1/+1 counter on it.)

Destroy target creature.

When Enter the Wormhole enters or leaves the battlefield, draw a card.
Whenever you cast a noncreature spell, target player mills a card.

You may have Enthusiastic Double enter as a copy of any permanent on the battlefield, except it's 4/4, it's a creature in addition to its other types, and it has haste.

Create two tokens that are copies of target noncreature artifact or noncreature artifact card in a graveyard.

This spell costs {1} less to cast for each artifact you control.
Choose two —
• Untap each artifact you control.
• Put a +1/+1 counter on each artifact creature you control.
• Draw a card.

Draw four cards.

Permanents you control are black. The same is true for spells you control and nonland cards you own that aren't on the battlefield.
At the beginning of your upkeep, you may pay {B}. If you do, you draw a card and you lose 1 life.

When Everything Is Going Great enters, create a 4/4 Elemental creature token that's all colors.
At the beginning of your end step, exile up to one other target nonland permanent you control, then return it to the battlefield under your control.

When Exergetic Chains enters, exile target nonland permanent you don't control and up to one target creature you control until Exergetic Chains leaves the battlefield.

Vigilance
{G}, {T}: Exile up to three target cards from graveyards. If two or more of those cards share a card type, create a 1/1 colorless Servo artifact creature token.

Each player sacrifices a creature.
Reconstruct {5}{B}{B}{B} (You may cast this from your graveyard for its reconstruct cost reduced by the mana value of a permanent you sacrifice as you cast it this way. Then exile this.)

When Expedition Outfitter enters, create a 1/1 colorless Servo artifact creature token.
At the beginning of each end step, if an artifact was put into your graveyard from the battlefield this turn, Expedition Outfitter deals 1 damage to each opponent.

Choose a color. Target player reveals their hand and you choose a card of that color from it. If you do, that player discards that card and you lose 1 life.

Destroy target artifact or enchantment. Surveil 1. (Look at the top card of your library. You may put that card into your graveyard.)

As Extinction Specialist enters, note two creature types.
Whenever Extinction Specialist enters or attacks, choose one of the noted creature types. Creatures you don't control of the chosen type get -1/-1 until end of turn.

When Extraction Mercenary enters, if you attacked this turn, crystallize. (Put a +1/+1 counter on a creature you control or create a Treasure.)
{4}{R}{R}: Extraction Mercenary deals 3 damage to any target.

Gain control of target nonland permanent until end of turn. Untap it. It gains haste until end of turn.

Choose one or both —
• Counter target spell.
• Exile target permanent you control, then return it to the battlefield under your control.
