There are some problems with the deck that are slowing the deck down, namely
- only 10 pendulums in 45 cards,
- 12 overly expensive cards in an underquantad deck,
- combo cards that clog the AI's hand,
- other clogging cards.
Now about the weaknesses,
- the creatures are fragile, each having 2-4 HP,
- sanctuary,
- earthquake,
- balanced mono CC decks,
- etc.
HOWEVER, the deck is pictured after a person, and no human is perfect, so maybe the best way is to leave the deck as it is, because it reflects that all of us have flaws(?). ^^"
