Honestly, this is one of the best features of the game, but unfortunately, the rewind won't take you back to the beginning of the match
You can use existing deck recipes (the ones you can load, anyway) as templates, add or remove monsters or Spells or Traps Or you can have fun and make Decks whose sole purpose is to bring out some monsters that are infamously difficult to summon (and which, sometimes, just arent worth the effort)
That reduces the depth of your deck just as youre making enemies by destroying lands
