Is this a good team for a Pokemon Tournament? (Black Version)?

Zoroark: Night Daze/ Dark Pulse your choice, I prefer Night Daze. Flamethrower stops Ferrothorn cold. Nasty Plot skyrockets its amazing Sp.Attack. Sucker Punch to hit weak defenses. Also, your Pokemon all temporarily go to level 50. Lilligant is a huge weakness on a team. All waters know ice moves, so I'd say you should go with the reliable Fighting type, Mienshao. I'll give Lilligant moves, and Mienshau. Lilligant: Quiver Dance to raise three stats at once, making it faster, stronger (Sp.Attack), and bulkier (Sp.Defense). Petal Dance, okay move, won't confuse with Own Tempo. Bad thing is, you get revenge killed easy, or give up a swap to a Fire type that kills you while you do squat. Energy Ball cause it doesn't uve the commitment. Last, but not least it gets Giga Drain for STAB recovery. Mienshao: First thing first, its ability is Regenerator. It evolves from Mienfoo. Mienshao should know U-Turn, to super effective hit Phsychic types, an regain some HP. Drain Punch to regain HP. Hi-Jump Kick as your main attack. And Brick Break for its reliability. Galvantula: Not to-shabby offensively, a piece of crap defensively. Won't last long, but take advantage of raised accuracy. Give it Thunder (high accuracy with ability) to wreak havoc. Bug Buzz is a good STAB. Energy Ball hits Ground/Rock (not to mention the common Water) hard. The final move is your choice. Vanilluxe: The only Pokemon where I don't want you to choose the item. Run a Choice Scarf to help it revenge-kill (found in Castelia City [only if you've traded with 30 people] or Battle Subway). Give this ice-cream cone Blizzard, and Ice Beam. Flash Cannon to take apart the Rock type, and most people run Taunt, but Hail could work (to increase Blizzard's accuracy). Chandelure: Broken. Give it Energy Ball, Shadow Ball, Heat Wave, Trick Room. You shouldn't use Swanna or Braviary, but I'll show Braviary: Sheer Force ability. Superpower, Brave Bird, Crush Claw, and Bulk Up works. Bad Pokemon though. If you want EVs told, just add additional details.
