Help with my pokemon team?

here is my final team, i just want to make sure nobody can see any major flaws in it before i go onto the elite four:

Espeon with the moves:
Psycic
Morning Sun
Shadow Ball
Return

Arcanine with the moves:
Sunny Day
Flamethrower
Dragon Breath
Dig

Heracross with the moves:
Endure
Reversal
Megahorn
Rock Smash

Tyranitar with the moves:
Crunch
Earthquake
Rock Slide
Iron Tail

Crobat with the moves:
Confuse Ray
Giga Drain
Fly
Double Team

Feraligatr with the moves:
Surf
Ice Beam
Blizzard
Strength

quote Dramon Knight

Only one thing really, take Giga Drain off Crobat and swap for Sludge Bomb, since Crobat has bad Sp.Atk and the Physical/Special split doesn't exist in this game. You get a base-130 Poison attack that way to use.

Thank you very much, this way my LP on youtube won't go up in flames too badly

Crobat does not learn Sludge Bomb in Generation II.
