Notes & Combos

Handtrap ratios look weird because i was usually swapping between 3x of veiler/ghost/fuwa at any given time.

Ghost Belle helps Mathmech a ton this meta because of the rampant Bystials, also provides protection for Superfactorial once you pass turn. Getting Sigma or Diameter banished is extremely bad so don't regret adding this card in.

For Main Deck, i run Defenser at 2x because I was drawing it too much, and it shares your normal summon with Diameter. Talents is my favorite card and board breaker so running as 1x, cutting the 3rd Small World since we have Cynet Mining back at 3x.

Gatchiri @Ignister is still the undefeated GOAT and searches your entire deck if you need a Small World target.

Extra Deck is pretty tight, I did consider 2x Laplacian and adding back Update Jammer at some points. Link Spider is cuttable but nice to have for Nibiru-reliant decks. I think Packbit is too good for non-destruction removal and he is now pretty much a staple in my ED, wins a lot of games.
