RequiemGurl's True Fairy Deck 2.0

This is a revision of this deck https://pokemoncard.io/deck/requiemgurl-s-true-fairy-deck-1-0-36902, having undergone a number of changes through extensive testing and a whole bunch of losses :D

OUT (-15)
Xerneas BREAK (-2): I found I was using Xerneas in a sacrificial way, to maximise how many times it used Geomancy and thus it never really used its BREAK attack, nor really benefitted from the extra 20 HP
Diancie (-2): It doesn't really have much of a purpose now the revision's down to 2 evolution

This is a revision of this deck https://pokemoncard.io/deck/requiemgurl-s-true-fairy-deck-1-0-36902, having undergone a number of changes through extensive testing and a whole bunch of losses :D

OUT (-15)
Xerneas BREAK (-2): I found I was using Xerneas in a sacrificial way, to maximise how many times it used Geomancy and thus it never really used its BREAK attack, nor really benefitted from the extra 20 HP
Diancie (-2): It doesn't really have much of a purpose now the revision's down to 2 evolution cards and new healing options have been added in its place
Escape Rope (-2): Their numbers has been halved to make room for 2 Switch Carts
Fairy Drop (-2): Whilst handy, they've been replaced with Switch Carts that provide more utility
Great Balls (-2): With the loss of evolutions, Trainer's Mail proved more useful
Professor's Letter (-2): They proved unnecessary with the energy acceleration from Xerneas and the Tag Team
Fairy Garden (-1): Tate & Liza, Escape Ropes and Switch Carts have all proven to be more useful
Parallel City (-1): I found most of my opponents weren't playing with a full bench anyway, so this often had little effect
Lusamine (-1): Her numbers have been halved, as it was frustrating (even more so than Pal Pad) to have two in the hand whilst there were no supporters or stadiums in the discard pile

IN (+15)
Tapu Fini (+2): I found 1.0 really struggled with strong GX, Tag Team GX, V and VMAX cards and with few Fairy-based options to knock them out, I figured the next best thing was to send them back into the deck so I could focus on knocking out my opponents' weaker benchsitting support mons. Their stall potential can also let me waste an attack to evolve Mega Mawile EX
Acerola (+1): Nothing's better than pulling a heavily damaged Tag Team back to your hand before your opponent can knock it out for 3 prizes
Ninja Boy (+1): This has a ton of uses, from swapping a heavily damaged multiprize mon for a single prize mon to deny additional prizes, swapping for something you can evolve or just getting support mons from the deck to the bench
Blunder Policy (+4): With the increased emphasis on coin flips, introducing some draw support softened the blow of losing flips
Glimwood Tangle (+3): These replaced the outgoing Stadiums to make sure I almost always get a redo on bad coin flips
Switch Carts (+2): These replaced the halved Escape Ropes and outgoing Fairy Drops and Fairy Garden, giving me healing and a free retreat
Trainer's Mail (+2): These are handy for thinning the deck and hopefully drawing something else to use back to back

The strategy for this version is to once again use Xerneas and the Tag Team to accelerate energy, Tapu Fini to stall my opponent by sending their heavy hitters back to the deck and to waste their energy with (Mega) Mawile EX, with a significantly increased emphasis on maximising coin flips
