This deck is anything but F2P. Even if you only use one Gozuki, you still have to search through Generation Next and Resonance of Contrast for Samurai Skull and Vampire Grace. Getting 3 cost rare cards easily 100 packs on avg minimum. On top of all the searching through Empire of Scarlets and Crimson Kingdom for Gozuki... one of the most expensive decks tbh. NOT F2P AT ALL.
If this is not F2P then you either A) wasted all your gems on 🔥 packs/boxes or B) have not been playing long enough. At most for 1 gozuki version it can take 500 packs which is 25k Gems considering you get 1820 for getting a character to lvl 35 you can make this from leveling 14 duelists (half the total number) and this is ignoring missions, events, ranked, and the gems they give out for free.
Not that I don't agree with you that this pack isn't THAT expensive, but I'm tired of people saying "Wasted all your gems on 🔥 packs/boxes." If you've been playing since release, the first packs weren't "🔥" at the time, as they were literally the only option. I'm not gem broke because I made bad decisions, but because I literally just played the game for too long.
Um... In your defense of how this deck is F2P, you show that it takes leveling HALF the duelists to level 35 to obtain the number of gems needed for the deck. Assuming there are the same number of gems rewards remaining from 35 to 45 on each character (Which there is not), that means that the gem rewards from getting 14 characters level 35 is 1/4TH of your total LIFETIME unlockable gems. Yeh, F2P.
