red mtg cards Rules Text: Devotion to red, 10 Auras you control Red MTG card's price spikes

Conclusion Thats it for my update to Mono Red Dragon Tribal with Inferno of the Star Mounts

By running any of Red's standard "loot" effects that discard to draw that many cards, like Demand Answers and Thrill of Possibility which cost us 2 cards to draw 2 cards, Inti can turn these card-neutral cards into card advantage by adding an "extra" card to the exchange

As the Princess of Friendship, it also makes sense that Twilights activated ability helps everyone (or every pony) win the game
