You may put a permanent card from your hand onto the battlefield. If it's a planeswalker, it enters 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.
Escalate {R}{R}(Pay this cost for each mode chosen beyond the first.) Choose one or more. You may choose the same mode more than once. • Culminating Chaos deals 2 damage to each creature and each planeswalker. • Exile the top two cards of your library and add {R}{R}. Until end of turn, you may play those cards.
Target instant or sorcery card in your graveyard gains flashback until end of turn. Its flashback cost is equal to its mana cost reduced by {2}. Conjure a card named Fatigue and put it on top of your library. (It's a colorless sorcery that costs {2} with “Draw a card.”)
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.
Choose two — • Exile the top two cards of your library. You may play them until the end of your next turn. • Add {R}{R}. • Creatures you control get +1/+0 until end of turn. • Flamecaller's Command deals 1 damage to each creature you don't control.
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.)
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.)
