As Nebula of Empty Gold enters the battlefield, choose two or more colors. You lose life equal to the number of colors chosen this way. {T}: Add one mana of any of the chosen colors.
When Miserable Portent enters, create a 1/1 black Harpy creature token with flying. {3}{B}, Sacrifice Miserable Portent: You draw two cards and you lose 2 life.
[+1]: Draw a card, then discard a card. [–2]: Fulmen, Aether Prodigy deals 2 damage divided as you choose among one or two targets. Draw a card. [–6]: Whenever you cast an instant or sorcery spell this turn, copy it. You may choose new targets for the copy.
Once each turn, when you gain life, you may exile the top card of your library. You may play that card this turn. Whenever you cast your second spell each turn, Ignition Engine deals 2 damage to target player or planeswalker.
As an additional cost to cast this spell, pay any amount of life. Search your library for a card. If you have 10 or less life, search your library for two cards instead. Put those cards into your hand, then shuffle.
Counter target instant or sorcery spell. If that spell is countered this way, exile it instead of putting it into its owner's graveyard. You may cast that spell for as long as it remains exiled and you may spend blue and black mana as though it were mana of any color to cast it.
Look at the top two cards of your library. Put one of them into your hand and the rest into your graveyard. Rerun (If you cast this from your hand, exile it as it resolves. Whenever a creature you control dies, you may cast this card from exile without paying its mana cost.)
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.
Escalate {R}{R}(Pay this cost for each mode chosen beyond the first.) Choose one or more.

You may put a permanent card from your hand onto the battlefield. If it's a planeswalker, it enters the battlefield with five loyalty counters rather than any other amount, and you may activate its loyalty abilities this turn any time you could cast an instant.
Whenever one or more +1/+1 counters are put on a creature you control, you may search your library for a creature card, reveal it, put it into your hand, then shuffle.
Put target permanent card with mana value 3 or less from a graveyard onto the battlefield under your control. Leitmotif (If you cast this spell from your hand, exile it as it resolves. When you next cast a spell that shares a color with this card, you may cast this from exile without paying its mana cost.)
When Curator of Cures enters the battlefield, adjudicate. (Create a white Aura enchantment token with enchant creature and “Sacrifice this token: Untap enchanted creature” attached to target creature.) Whenever an Aura enters the battlefield under your control, you gain 1 life.
