>>28764433Always keep in mind the strategy of your team. Be it positional out-trading, endgame setups or
rolling the dice, find a strategy that works best with both your skill level and the format. I know it sounds obvious, but many a good player has lost track of team synergy while pursuing perfect Team Type Charts, and while playing, the superficial goal of knocking out all of the opposing Pokemon on your opponents team.
Also, I'm sorry, but Hariyama really does not do even decently at all in both Singles and Doubles. Good luck, anon.
