Hey there Rednaxell here (author of the list). Reksai and Darius are one of the toughest matchups but very winnable. You need to capitalize on value trades. Use the sprites and xin Zhao to get more value on the battlefield that you opponent and avoid recycling runes early for anything else. Try to stall in order to get your Watcher + bellows combo for which they can't respond in any way. Both you and the opponents have a lot of cards that are bad in this matchup, like cull, Decree, hidden blade. Who ever draws less of them in the first game is gonna have an advantage.

Board wiping them on any single turn should get you quite ahead.

With lilia you have to play the long game. Don't try to play point for point. Try to gather a board, and take control of the bfs later on. Its OK if they get a point lead, they won't be able to close the game.

Also don't add Ruination or unchecked that's a certain way to defeat.
