Notes & Combos
Not sure if Centur-ion is the best, but it is my favorite. Centur-ion just has too many in engine "Bricks". No Bonds or Awakening because they just compound that problem. Another problem is that Centur-ion can often fold to 1 hand trap, so I played the PUNK package to give some extenders/starters. It also has issues going second into boards if you didn't hand trap them to death. I didn't like the bystial package because they aren't hand traps since I faced mostly Tenpai, Crystron, and ice barrier, and speedroids. Bystials don't do a ton in the mirror. Maxxed out on the best hand traps and sprinkled the others in. Lots of random 1 ofs for crossout and to not draw multiples of them. They usually worked out and this deck does need fodder to discard.
Never summoned: Berserker or Sifr. Berserker was in theory my idea if I had to summon something level 8 on their turn and didn't have anything to discard for Packbit. People told me the Sifr could be good against tenpai, but Blazar is better blind. Tenpai only one when they hand trapped me to death anyway. Ancient fairy dragon and the second Legatia only came up once, so it could be replaced.
Overall, it is fun to drop big bodys on board, but you gotta be aware of the weaknesses.
