Chroma — Reveal the top ten cards of your library. For each blue mana symbol in the mana costs of the revealed cards, target opponent mills a card. Then put the cards you revealed this way on the bottom of your library in any order.
Target opponent reveals their hand. You choose a green or white creature card from it. You gain life equal to that creature card's toughness, then that player discards that card.
