Notes & Combos
All board breakers, no handtraps. Ratios are nice. Hardest matchup is against Labrynth because they can easily -1 your hand, and this deck is all-in. (If you have Red Reboot and Thrust, use it, I don't have the UR to craft them so sadge.)
Honestly you won't really be using the Extra Deck that much, most of the time they're just fodder for PoE. But it's still good to put generic toolbox monsters that could help you pilot the deck.
Matchups:
Kashtira - 80/20 (easiest matchup lol)
Purrely - 90/10 if you have Lava Golem or Kaiju + Backrow Removal, but otherwise it's 70/30 to 50/50 depending on the hand.
Spright Variants - 70/30 to 60/40 depending on the hand.
Tearlament Variants - 60/40.
Rikka Sunavalon - 60/40 but 80/20 if you started with a Kaiju/Lava Golem + Backrow Removal.
Mathmech - 60/40 because of that stupid trap that makes you go -1, sometimes you get lucky though.
Labrynth - 50/50, but I assume it's going to be 80/20 if you have Red Reboot (I don't).
