I see at least three teams in that screenshot that should be "easily" beatable, and another one team that seems like it could be a coin flip.
The three that aren't running speed leads (#1, #5, and #6) should be no problem with a cookie-cutter speed nuke team. Of course I won't know that for sure until seeing their team power, but since they aren't running speed leads, you should easily win the speed race, and if they're at that level, I expect they aren't running resist either.
The coinflip one would be team #4, which is running Gorg as lead, but without a second speed booster or other factor to compensate. Depending on how fast the Gorg and rest of the team are, you may not be able to out-do them with a speed nuke team.
FYI - cookie-cutter speed nuke team is one of two types: either running a single speed booster as lead, or having two speed boosters. Typical setups are Khatun lead, Spirithost, Warmaiden, Kael, and Khatun lead, Apoth, Warmaiden, Kael. The latter team requires your Kael to be geared quite well, though the fact that you have two speed boosters means you can sacrifice your speed boots in favour of ATK % boots.
