The current deck strategies in Standard focused on the midrange approach based on the clan colors. In effect, they tend to start slower and most of their spells are played on the third turn. In this effect, aggro decks like Red abuses this matchup as they usually start faster and beat them before they stabilize.

Another speedy deck that I would recommend is the archetype that adopted a mechanic from Theros Block: Heroic. This version utilizes the colors Blue and White whereas the popular builds are based on Red and White. Blue is preferred for evasion, card draws and sideboard counterspells.
