Aurora M3W (+ Solgaleo-GX et al)

Here's an update on a previous Aurora "M3W" (that is, "Mewtwo & Mew") build linked here: https://pokemoncard.io/deck/?deckid=2565

After playing the earlier version, I noticed that I hardly ever needed Great Catcher and Mallow & Lana, or at least they never made any game-changing impacts.  So, I cut those two and added one more Fighting Fury Belt, plus a Solgaleo-GX.  After losing to another Aurora M3W deck's amazing Sunsteel Strike attack, I realized this card was a must.

After playing the earlier version, I noticed that I hardly ever needed Great Catcher and Mallow & Lana, or at least they never made any game-changing impacts.  So, I cut those two and added one more Fighting Fury Belt, plus a Solgaleo-GX.  After losing to another Aurora M3W deck's amazing Sunsteel Strike attack, I realized this card was a must.  Indeed it is -- discarding all your energy for 230 damage can really help close out that final KO. 

Fighting Fury Belt is also crucial to Mewtwo & Mew-GX's impact.  So, now there's two of them.  In a close match, you'll often need to play two Mewtwo & Mew-GX's, as one of them will get KO'd.  You'll almost certainly lose one of your Fighting Fury Belts thus, so here's another to keep up your momentum and help recover after that KO. 

Naganadel & Guzzlord-GX remains a vital contributor.  Not only does it's Violent Appetite ability help discard certain attackers.  It's GX attack can also quickly change the tide of the game, since it awards two prize cards pretty much for free.  With Dimension Valley in play, you'll only need two energy attachments to make that happen.  The same goes for it's Jet Pierce attack for an impressive 180 HP.  That attack helps a lot when you need to Boss KO a Dedenne, Crobat, or any other pesky two prizers from your opponent's bench.

Altogether, this deck provides countless pathways to win.  Plus it's just a lot of fun to play.  If you're trying it out and happen to win the coin toss, I'd suggest going second.  It's draw engine is such that you could feasibly Field Blower away your opponent's Chaotic Swell or Path to the Peak, set up your own stadium card, get M3W into the active spot with some energy, and cause some serious damage to your opponent's active and even their bench if you're able to mobilize your Giratinas... all on turn one!  Enjoy :-)
