I am encouraging 3-color decks with a high amount of lands to account for a lack of fetches. Searching exists in small doses of green ramp spells and reanimation enablers. My hope is that this will result in fewer non-games and mulligans, without completely nullifying the advantage of a streamlined aggressive deck.
