To teach my Mega Charizard Y Thunder Punch or Solar Beam ?

Question

I was thinking about what move is better for my Mega Charizard Y , Thunder Punch or Solar Beam ?
Both moves give my Charizard coverage against water types.
About my Charizard:
Stats:
HP:241
Attack:185
Defense:198
Special Attack:193
Special Defense:153
Speed:159

Nature:Relaxed
Ability:Blaze
Item:Charizardite Y

Moves:
Fly ( better dont ask about Fly )
Dragon Claw ( this is the move that I want to replace with Thunder Punch or Solar Beam)
Earthquake
Flamethrower

I think I choose Solar Beam because Mega Charizard Y's ability make Solar Beam to strike in one turn or maybe Thunder Punch is better for my Charizard, I am not a expert in Pokemon so is a little hard for me to decide.

Answer 1

Solar Beam is the way to go. Not is it only more powerful than Thunder Punch, but it strikes with no charge turn! Here is a set:

Charizard @ Charizardite Y
Ability: Drought
EVs: 252 SpA / 4 SpD / 252 Spe
Timid Nature
IVs: 0 Atk
- Fire Blast / Flamethrower
- Solar Beam
- Air Slash / Dragon Pulse / Focus Blast
- Roost

Comments

You got solar beam right but air slash is pretty pointless as flamethrower hits the grass and bug types that air slash does and hits way harder than air slash
I would replace it with some coverage maybe for dragon pulse which hits dragons that resist flamethrower or hidden power ice for garchomp and landorus which are popular pokemon

---

Focus blast is more popular than either of those moves because not all rock Pokemon are weak to grass, and it's good for defeating Heatran. As for air slash, I think it's used because Charizard has no better answer for fire Pokemon.

Very true my good sir

---

Yes, but Focus Blast has terrible accuracy.

---

It's better than Charizard's other moves.

---

I picked Heat Wave for a fire-type move, and Solarbeam, Air Slash, and Protect...

---

Unless you're playing doubles, protect sucks on Charizard. All it does is stall out its own sun turns, giving it fewer chances to use a sun-boosted flamethrower or solar beam.

Answer 2

I'd give it SolarBeam. Mega Charizard Y already has WAY higher Sp. Atk than Attack, and Thunder Punch is both a physical move, and is almost twice as weak as SolarBeam to begin with. Plus, it has an ability that is essentially a Sunny Day that doesn't waste a turn. In other words, Sunny Day will hit instantly, backed up by Mega Charizard Y's decent speed (higher than many water types anyway), allowing it to counter water type Pokemon. It can also allow it to counter the rock types that cause it so much pain due to Stealth Rock and Stone Edge, as rock types are also generally very slow and have low Sp. Def.
