Hello Smogon users, I'm quite new to USUM after quitting somewhere in the middle of ORAS. After seeing that mega Mawile was unbanned for this generation I decided to see if it was as devastating as in early XY. This thing hits like an absolute truck, totally decimating fat teams. This is my first real attempt at a team this generation so any help is much appreciated! Lets get into the team!
In Depth:
Here's the star of the show, 4 attack mega mawile. I decided to go with an all out attacker because of the sheer power that this monster has. It is so slow that it is basically a sucker punch machine after it gets the SD on a switch, so to me the added coverage was much more valueable. I decided to go with sucker punch over steel stab because I think that priority is still nice to have against offense so at the very least it can get a revenge kill or chip damage on something for a shuriken sweep.

I decided to pair Mawile with koko for a few reasons. First off, mawile struggles vs offense generally and koko is arguably the biggest pain for offense to face. Second, i couldn't resist the electric terrain Tpunch combination. I went with a more utility set because of how important koko often is in the battle. its nice to get a roost on a forced switch to keep this monster healthy, also for the fact that I don't have the most reliable hazard removal. I personally prefer the u-turn over volt switch because it allows koko to pick up momentum regardless of if they have a ground type.

With 4 attack mawile, I wanted two things in this spot. First I knew i wanted spikes on this team because chip damage is often very important for koko and mawile to ensure ko's. Second,I wanted a more reliable sweeper. Greninja seemed to fit the bill because it is the go to for offensive spikes, but also because of how much pressure mawile and koko can put on the typical greninja counters. its is so easy to double to Mawile and get a free hit every time ferrothorn, bulu, tangrowth, magearna, etc. come in to try and check this beast.

The team was very clearly needed a ground immunity and a more reliable fighting resist than koko so landorus was added to the team. It ended up being scarf landorus because even with greninja and koko I still wanted a little more speed control, and it makes it a more reliable u-turn user. Defog is the fourth move here just in case the opponent manages to get hazard stacks. Hp ice over stone edge is to stop zygarde from just destroying me after one dd, although this is not even a real answer to that monster.

The team auto lost to rain at this point, and also needed a reliable blanket check to the normal offense killers like koko and ash greninja. Tangrowth fit nicely here as regenerator lets it take a beating, but still be a reliable switch in when needed. The set is very standard, and I opted for the HP Ice to help a little bit more with the Zygarde MU a little more.

The last mon added was Heatran. This is the spot I still cant figure out on this team. I went with heatran because as it was the team did not have a rock setter yet nor did it have a steel type. Heatran adds a lot of pressure to the steel and grass types that give greninja. The bad news for heatran is that it compounds the teams weakness to ground moves, which can be pretty annoying. Honestly I think a more valueable pokemon can be in this spot, and hopefully a rater can help me!

Again, any help and suggestions will be taken into consideration as I'm still quite new to USUM and want to get back into the swing of things. Thank You!
