My take on a 50-card pile for the newly releasing White Woods archetype.
They synergise really well with Centur-Ion, and the Toy engine allowing themselves to special summon themselves when they're sent for a White Woods effect is also just free bodies on board for I:P/S:P, or if you're desperate for the synchro material for Centur-Ion Auxila or Legatia, dependent on hand quality.
Centur-Ion in of itself as an archetype is just stupid. Synchro-ing on your opponents turn for a free calamity lock into game is ridiculous, and Stand-Up Centur-Ion!'s ability to synchro summon during your opponents turn off a special summon makes the Silvera Book of Moon effect live and very scary for your opponent to come up against.
I had also tested this deck at 43 cards, however it felt weaker than the 50-card pile. You're wanting to see either Centur-Ion or White Woods cards in hand and whilst the 43 card deck was more consistent in having full combo, the lack of hand-traps and over-reliance on setting up a board that can get you access to Calamity tipped the 50-card pile in my opinion.
The side deck is purely aimed at my locals. Please change this to your own tastes if you are copying the deck.
Your best hand is seeing Risette with a White Woods spell or trap, as they can set themselves for when you add Asteria.
Most common hand is seeing a Centur-Ion name like Trudea/Primera without the Stand-Up!
Your worst hand is just seeing pure hand traps. However that's the beauty of this 50-card pile is that whatever your dead hand is you can definitely still interact with the game.
