When you expect the game to be decided before you play all your cards like in many aggro decks and gambling with your worst card is worth it to try and upgrade your options
UR Ultra Rare Performapal Barokuriboh X DARK Level 8 [ FiendPendulumEffect ] ATK 300 DEF 3000 P Scale 1 Once per turn, at the start of the Battle Phase: You can add 1 monster with 300 ATK/200 DEF from your Deck to your hand, then destroy this card
One two-drop enables a big Rakdoss Return as early as turn 4
In many decks, they end up being the anchor of the strategy, whether thats reanimating creatures, looping spells, or enabling anything from cost reduction to card draw
I'm playing all of these cards because I need to keep my opponents in check while I get read to setup my big splash play
Another deck I was worried about was Bogles as it has increased in popularity quite a bit since it's Grand Prix Toronto win earlier this year
