Long time, no speak, Goke. Hope all is welll for you. Where is the correct place to post this 5th gen single Poke analysis?
Tentacruel @ Black Sludge/Leftovers
Nature: Modest
Ability: Liquid Ooze
IVs: 252 SpAtk/252 SpDef/4 HP
Moveset:
-Acid Spray
-Giga Drain
-Scald/Surf
-Hidden Power Fire/Ice Beam
If the opponent dosen't have a lead Poke that can either Earthquake, or ThunderPunch Tentacruel, you start out with the upper hand in the battle, no matter what else they might do. Acid Spray to immediately drop SpDef by 2 stages, the KO with move of choice. Giga Drain is your second main atacking option here, to gain back any lost HP. Scald to try and burn, or Surf for more power, both for a second STAB move. HP Fire for steel types, and Ice Beam for Dragon types, deoending on what your team is weaker against. Most people will also try and Taunt this lead, thinking it is running Toxic Spikes, so more often than not, you will get a free shot in.
