yugioh legendary deck king of games Yu-Gi-Oh! Games: Yugi's Decks Collector's Set (2019) may be 1st or Unlimited Edition Berfomet - King of Games:

SR Super Rare Limited Limited Tearlaments Merrli X DARK Level 2 [ AquaEffect ] ATK 800 DEF 2000 If this card is Normal or Special Summoned: You can send the top 3 cards of your Deck to the GY

Who would have thought a mere bird with just 300 ATK would interrupt the game to the extent that the game makers had little choice but to ban the card from competitive play

PSE Prismatic Secret Rare Centur-Ion Trudea X DARK Level 4 [ PyroEffect ] ATK 1000 DEF 2000 During your Main Phase: You can place this card you control and 1 "Centur-Ion" monster from your hand or Deck, except "Centur-Ion Trudea", in your Spell & Trap Zones as face-up Continuous Traps, also you cannot Special Summon "Centur-Ion Trudea" for the rest of this turn

It is an incredibly swingy card that is often well worth some of the risks of playing it
