At the beginning of your upkeep, create a Treasure token. Then if you control fifteen or more artifacts, creatures, and/or enchantments, you win the game. (Treasure tokens are artifacts with “{T}, Sacrifice this artifact: Add one mana of any color.”)

{X}, Exile Mysterious Coffer: Return all nonland permanents with mana value X or less to their owner's hands.

{T}: Add {C}.
{T}, Reappropriate: Add {B} or {R}. (To reappropriate, exile exactly two cards from your hand and/or graveyard.)

Each opponent sacrifices an artifact, an enchantment, and a creature with flying.

First strike
Manifold Manipulator has lifelink as long as you control a white permanent. The same is true for flying and blue, menace and black, and trample and green.

Dominance — When Dragon Queen's Pupil enters, put a +1/+1 counter on it if you control the creature with the greatest power or tied for the greatest power.

When Jeffery Stages the Finale enters, search your library for a legendary blue card, reveal it, put it into your hand, then shuffle.
Whenever you cast a spell with mana value 5 or greater, return up to one target nonland permanent to its owner's hand.

Hexproof
As long as an opponent controls a permanent you own, Vault Sentinel gets +4/+4.

Move any number of +1/+1 counters from creatures you control onto target creature you control, then that creature deals damage equal to its power to target creature you don't control.

Draw a card. The next noncreature spell you cast this turn costs {2} less to cast.
Showcase {3}{R} (Then if you cast this for its showcase cost, create a 1/1 red Bard creature token that can't block and exile this. Whenever it attacks, you may cast a free copy of this.)

Discard a card, draw a card, then conjure a card named Data-Point into your hand. (It's a sorcery that costs {2} with “Draw a card.”)

Whenever another Knight or Soldier you control enters, target player loses 1 life.

Target player sacrifices a legendary creature or planeswalker.

Flying
When Trove Tyrant enters, exile the top five cards of your library.
Whenever Trove Tyrant deals combat damage to a player, you may cast an artifact card exiled with it without paying its mana cost.

Trial 4 (As you cast this spell, an opponent of your choice may pay 4 life. If they don't, they fail the trial.)
You draw two cards and you lose 2 life. Target player discards two cards if they failed the trial.

Pierce the Sky deals 7 damage to target creature with flying.

Rhapsody {4}{W}{W} (Pay {4}{W}{W} to cast this as a 4/4, or as a sorcery to make it become a 4/4.)

Draw a card.
Foretell {W} (During your turn, you may pay {2} and exile this card from your hand face down. Cast it on a later turn for its foretell cost.)

{2}, Exile a land card from your graveyard: Create a token that's a copy of that land.

First strike
Whenever Keeper of the Banner deals combat damage to a player, draw two cards, then discard two cards.
