Heatran is back! Did you get one last time? Did you get a shiny? If not, you probably want to get some. For PvE, it shows up as a top tier counter in many raids, it’s bulky, and its steel type provides some extra resistances to give it time to deal decent fire damage. For PvP? It has some wins, but it also can get stomped pretty hard, it isn’t used a lot, but you could build a team around it and have fun.
How to beat this raid? Some of these counters were just in the december community day, and most don’t need the exclusive move if you missed it. I hope you made some Garchomp, it’s going to pay out in the long run. Oh, and that maxed perfect swampert without community day move? Dust it off and say it wasn’t wasted after all.
