Update: Added a new Pokemon to replace Chansey (rip cleric). Metagross acts as the lead of the team as well as a safe switch-in to potential threats such as Gyarados, Heracross and Venusaur. I have calculated the moves these enemy Pokemon can do to Metagross and it seems their best move VS an AgilityGross wouldn't do an OHKO even with critical hits. At best, they can only do guaranteed 2HKOs. However, Gyarados is the only Pokemon who can't 2HKO Metagross even with crits.
