Instead of receiving protection itself, "Cehrmba" forsakes the first effect from the above list and instead prevents your Fusion Monsters from being destroyed by card effects while you control it
Because of this, cards that don't Special Summon on their first turn always contain this card
Part of that issue is to do with the rarity of the cards, with a vast majority of the cards that you need for the deck being a Super Rare or an Ultra Rare, and all of the necessary cards being dotted around various different packs
Any sane player would try to get rid of the traps first before trying to send more cards to the graveyard, but the AI will happily kill itself in such scenario
Bandai really loves Imperialdramon and to be fair, who doesnt
If you use Chusapo as a material and draw while destroying it, you have a huge advantage
