Tangela

Tangela’s Grass-typing is great for taking down Water-type raid bosses. It holds its own against Blastoise, Vaporeon, and Rhydon. One of Tangela’s assets is lack of Poison-typing, compared to Venusaur, Victreebel, and Vileplume, which aids its performance against Ground-types. However, Tangela’s stats are slightly worse than the aforementioned Grass-types, so it ends up being solid, but nothing special.

Best PvE Offensive Moveset

• Vine Whip is superior to Infestation for filling Tangela’s niche as Water-type slayer. Infestation has lower DPS and poor type coverage.  

• Solar Beam is superior on offense for raw damage.

• Power Whip and Grass Knot are of similar power level to Solar Beam, but outputs a bit lower damage. Both have the advantage of being 2 bars.

• Sludge Bomb is generally inferior for lack of STAB and poor type coverage.

Best PvE Defensive Moveset

• Infestation is superior to Vine Whip on defense for raw damage and better counter coverage.

• Sludge Bomb is a good consideration for defense to do neutral damage to Tangela’s counters.

• Power Whip and Grass Knot are good choices for defense for the low charge time.

• Solar Beam is very easy to dodge, and should not be considered for defense.

Vine Whip is Tangela's best fast move option, providing good damage and energy generation. Sludge Bomb is your non-Grass option, making it mandatory for coverage. Grass Knot is run over Solar Beam because it's cheaper, and thus more consistent. Power Whip, Tangela's legacy move, has identical stats to Grass Knot, and thus can be run by preference if you have one.
