Create three tapped colorless Powercell artifact tokens with “{T}: Add {C}.” Then untap all artifacts you control. At the beginning of the next end step, sacrifice three artifacts.

Enchant land
Enchanted land has “{T}: Exile the top card of your library. If it's a nonland card, you may cast that card this turn.”

Copy target instant or sorcery spell you control. You may choose new targets for the copy.

Each creature has haste and “At the beginning of combat on your turn, choose an opponent at random. This creature attacks that player this combat if able.”

Whenever a player casts a spell from their hand, that player exiles it. Then they cast a copy of a card exiled with Embrace the Unpredictable chosen at random without paying its mana cost.

Up to two target creatures can't block this turn. Exile the top two cards of your library. Until the end of your next turn, you may play those cards.

Create X 1/1 red Soldier creature tokens with haste.

Enchant creature
Enchanted creature gets +1/+0 and has menace and haste.
You may cast Empty the Magazine from your graveyard by paying {3}{R} rather than paying its mana cost.

Choose one —
• Creatures you control get +2/+0 until end of turn.
• Creatures your opponents control can't block creatures with less power this turn.

Untap each creature you control. After this main phase, there is an additional combat phase followed by an additional main phase. At the beginning of your end step, sacrifice each creature you control that attacked this turn.

Each player discards their hand and sacrifices all permanents they control, draws seven cards, then abounds seven times. (To abound, you may cast a spell that costs less than this from your hand without paying its mana cost.)

As an additional cost to cast this spell, sacrifice a creature.

Enchanted creature gets +2/+2 and has trample.

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.

Whenever a player casts a spell, exile the top card of that player's library. You may play that card for as long as it remains exiled, and you may spend mana as though it was mana of any type to cast it.
At the beginning of your end step, put all cards exiled with Endless Inspiration into their owner's graveyards.

Gain control of target creature with mana value 4 or less until end of turn. Untap that creature. It gains haste until end of turn.

Catalyze. (The next spell you cast this turn costs {1} less to cast.)

Engulf in Flames deals 1 damage to target player and each of up to three target creatures that player controls. Those creatures can't block this turn.

Once each turn, when you cast a spell, you may note one of its card types that hasn't been noted for Enter Captain Minnow. If you do, create a number of tapped Treasure tokens equal to the number of types noted for Enter Captain Minnow.

Up to one target attacking creature gets +3/+3 and gains trample until end of turn.
Harmonize. (Trigger up to one harmony of a permanent you control.)

Entropic Inferno deals 5 damage divided as you choose among any number of targets. At the beginning of the next end step, for each permanent dealt damage this way, its owner puts it on the bottom of their library, then reveals cards from the top until they reveal a nonland permanent card. They put that card onto the battlefield, then shuffle.
