Due to Arena Trap being banned from OU recently, I decided to make a new thread to discuss the new metagame. Arena Trap had a decently big effect on the metagame, as it prevented some wallbreakers from seeing as much usage as they'd like, and it also caused people to resort to using Shed Shell on mons like Toxapex. Now that Arena Trap is gone, the mons that were most affected by Arena Trap now have a new opportunity to shine in OU, and I will go ahead and list them below. Keep in mind that the complete list of mons affected by Arena Trap is far greater than what's below, as depending on the situation, any grounded mon could be revenge killed or finished off by Dugtrio (the most common Arena Trap user).
Offensive mons:
Most of these mons would get trapped after they KO'd a target. In most cases, Earthquake from Dugtrio would immediately KO them, but in other cases, Focus Sash on Dugtrio would allow it to survive a hit and then KO in return with Earthquake or Reversal.
Defensive mons:
Depending on the sets and EV spreads, Dugtrio had the potential to 2HKO all of these, especially if they were to have their item knocked off or if they were statused and/or chipped into Earthquake range. In most cases, these mons would be unable to 1HKO Dugtrio in return, which would allow Dugtrio to 2HKO them before being KO'd itself.
Finally, I'll leave some questions below:
1. What mons from above do you believe will see a spike in usage?
2. Which mons do you think will be overhyped and have their usage die down after a few days/weeks?
3. What mons not included above may do you think will see more usage in OU?
4. Aside from Arena Trap users (Dugtrio, Trapinch and Diglett), is there anything that may see less usage now that Arena Trap is banned?
5. How do you think the metagame will develop now that Arena Trap is banned?
6. Is there anything that may become too problematic for OU now that Arena Trap is banned? Don't go overboard with this one.
