Win Conditions

The main goal of the MU is to gain stage control, hold your space, and edge guard Pythra, as while she has the stage it is very hard to contest her position, which means you need to play slow and cautious

Focus

Landing simple but effective reads in order to keep Pythra away from stage as much as possible, be it Juggling or ledge trapping

Neutral

While in neutral, Pythra always has advantage, with fast long normals that G&W cannot up b OOS effectively, keep to the ground and approach with shield in order to mess up their spacing and gain an advantage, Pythra's main options are almost always going to outrange yours, so play a Punish game on her more committal options

Disadvantage

Ledge

• Mythra has very fast options and can cover ground quickly, however is not the main threat at ledge do to having low knockback and being focused more on combo tools, albeit that does not mean you can take her ledge trapping for granted as it can rack up damage quickly if you aren't careful
• The main threat at around 60% is Pyra, with, in my opinion, the most annoying move in the toolkit, F Tilt, covering space, coming out quickly, and being completely safe on shield when spaced, not to mention that it sends at an awful angle and kills relatively early, instead of contesting Pyra at ledge, I've had much more success getting around her and to the other side of stage to reset to neutral, which is easier to contest than Mythra

Juggling

• Hold in on Mythra combos. You will get sent high, and she will have a harder time following up.
• Mythra has much more success juggling than Pyra, as she can move quickly to your position and keep you in the air for a long time, the best option usually being going to ledge to swap them to Pyra, as her movement is slower enough to be reasonably contested on the reset to neutral, Pyra, like Mythra for ledge trapping, should not be taken for granted while being juggled however, as a few good up airs can get you killed at 70%

Advantage

Ledge

On ledge, Pythra has a pretty good get up attack that makes bacon need to be spaced properly, and Mythra can foresight through bacon ledge trapping, most other options are beat out by basic bacon routing however, making this the most basic part of advantage, be aware that Pyra will try to cheese an up b kill at ledge if you aren't careful

Offstage

Pythra has a bad recovery against G&W offstage, with up b beat out by bair in most cases and Mythra side b getting beat out by G&W up b, landing these hits can make securing an early kill very easy, and shift the tide of the battle to your favor

Juggling

Pyra has low drift and is much easier to juggle with up air, making Pyra the best to get into disadvantage, Mythra however can foresight up air pretty reliably, especially after getting hit by up b, making Juggling much harder to set up against Mythra, done correctly, the goal is to force them offstage then land an early kill with bair or up b

Misc.

• Mythra nair has a landing hitbox, the number of times I've forgotten this when I think Mythra didn't space the nair on my shield is staggering, be as patient with your up b's as possible

• Unless Pythra is very close to your shield, there is no reason to up b, instead try and Punish the second move they throw out on shield as that will more than likely be less safe, especially when Pythra is on the approach

Stages

Mythra prefers stages with combo potential and maneuverability, whereas Pyra prefers stages in which she can corner you easily with her large hitboxes, because of this, it is better to choose your counter picks based on preference of which one you feel you play better against

Battlefield

• Mythra favored

Final Destination

• Pyra Favored

Town and City

• Layout Dependant, tri-plat Mythra, ledge plats Pyra

Smashville

• Perhaps the most even, as the large center plat provides good space for G&W to move, without making Mythra's combos to extensive

Pokemon Stadium 2

• Similar to Smashville, but more Pyra favored as her large hitboxes can cover most, if not all, of plat

Kalos

• Pyra Favored
