Mega Charizard Y Raid Duo Guide

Mega Charizard Y can do almost nothing to Mega Diancie. This thing resists everything that everyone's favorite not-a-dragon can throw at it, and has the highest DPS of any counter that's not determined to break its skull on Mega Charizard Y.

• Strengths: Fire Spin, Air Slash, Dragon Claw (2x), Fire Blast, Overheat
• Weaknesses: None

If Mega Diancie doesn't care what Mega Charizard Y does to it, then Mega Tyranitar isn't even aware of this fire-lizard's existence. This monster has tremendous TDO that outlasts everything in the game, and its DPS is great to back that raw power up.

• Strengths: Fire Spin, Air Slash, Fire Blast, Overheat
• Weaknesses: None

While it isn't quite the best rock on the block, Mega Aerodactyl is a great backup.

• Strengths: Fire Spin, Air Slash, Fire Blast, Overheat
• Weaknesses: None

Please, please don't TM away Dragon Ascent for Ancient Power. Mega Rayquaza is solid here, but it's definitely not worth such a tremendous cost!

• Strengths: Fire Spin, Fire Blast, Overheat
• Weaknesses: Dragon Claw

Mega Aggron has lost its Rock typing, but it can still hit hard despite a lack of STAB.... even though it's weak to Fire now.

• Strengths: Air Slash, Dragon Claw
• Weaknesses: Fire Spin, Fire Blast, Overheat

Shadow Ramparados is an incoming asteroid, streaking across the sky with the sole goal of bringing about the extinction of a certain flaming reptile.

• Strengths: Fire Spin, Air Slash, Fire Blast, Overheat
• Weaknesses: None

The hulking TDO/DPS mix itself, Shadow Rhyperior causes heavy damage to Mega Charizard Y and lasts a very, very long time.

• Strengths: Fire Spin, Air Slash, Fire Blast, Overheat
• Weaknesses: None

While not quite as much of an extinction-level event as its Shadow, Ramparados still does heavy damage.

• Strengths: Fire Spin, Air Slash, Fire Blast, Overheat
• Weaknesses: None

A bit overlooked, Shadow Gigalith is a very strong Rock Type with a great mix of DPS and TDO. It's hard to go wrong when adding it to your team.

• Strengths: Fire Spin, Air Slash, Fire Blast, Overheat
• Weaknesses: None

One of the once-and-former kings of the Rock Type, Shadow Tyranitar has fallen off a bit in the face of the tremendously powerful Shadows that it directly competes with. However, it's still an outstanding Pokemon that puts in great DPS and TDO alike.

• Strengths: Fire Spin, Air Slash, Fire Blast, Overheat
• Weaknesses: None

An old-fashioned Rock titan, Rhyperior still has the muscle to counter Mega Charizard Y pretty hard.

• Strengths: Fire Spin, Air Slash, Fire Blast, Overheat
• Weaknesses: None

Terrakion's Fighting sub-type means that it loses Rock's resistance to Air Slash, but it's still fine.

• Strengths: Fire Spin, Fire Blast, Overheat
• Weaknesses: None

T-REX-ROCKS

• Strengths: Fire Spin (2x), Air Slash, Fire Blast (2x), Overheat (2x)
• Weaknesses: None

Shadow Aggron doesn't resist Mega Charizard Y's Fire Type moves, so its average performance tends to fall off. Still, at least it double-resists Air Slash and resists Dragon Claw as well, so that's... something?

• Strengths:  Air Slash (2x), Dragon Claw
• Weaknesses: None

Shadow Omastar has one of the best possible typings to counter Mega Charizard Y, but its damage output is a little bit lackluster.

• Strengths: Fire Spin (2x), Air Slash, Fire Blast (2x), Overheat (2x)
• Weaknesses: None

• Strengths: Fire Spin, Air Slash, Fire Blast, Overheat
• Weaknesses: None

Shadow Aerodactyl has good DPS, but its TDO is one of the lowest among Mega Charizard Y's top counters, on average.

• Strengths: Fire Spin, Air Slash, Fire Blast, Overheat
• Weaknesses: None

• Strengths: Fire Spin, Air Slash, Fire Blast, Overheat
• Weaknesses: None

• Strengths: Fire Spin, Air Slash, Fire Blast, Overheat
