Forretress

Much has changed with the shift to BW, but Forretress is still Forretress. It remains exceptionally good at what it does, namely providing entry hazard and Rapid Spin support, but outside of that role, it is extremely limited. BW brought it a few buffs in Volt Switch and the improvement to Sturdy, which now acts as a pseudo-Focus Sash. Sadly, threats such as Reshiram and Magic Bounce Xatu have also come into play, making life a bit harder. All in all, play safe, support Forretress well, and watch as your opponent is shredded and poisoned at every turn by layer after layer of entry hazards. Be a bit careless and predict wrongly, though, and shudder as your bagworm is wiped out every match without fail.
