>>52290528First of all, speed is the most important stat in this game.
Bundle has the highest speed in the tier outside of pult (who fell off). Bundle has perfect neutral coverage with Hydro and Freeze Dry, nothing resists this combination.
Bundle has access to energy booster to reach 560 speed so he can revenge kill mons.
Any defensive units will get encore'd and made setup fodder.
He counters Palafin and at the same time helps him out a ton by baiting water resists and blowing them out with freeze dry, Slowbro gets OHKO'd
Here's a match in the 1600
