I'm already at the 16th Floor but going to accumulate massive amounts of keys to blaze through this event quickly so I can get Axel and all the rewards at least once so I can save my Duel Orbs for the 5D's Duelist Chronicles event.
I'm just gonna blaze through 18, get the Mat, 22, get Axel, and 33, get the Icon.
Then bow out.
Getting extra copies of Mars isn't my Priority nor is making it Prismatic.
My real priority is Duelist Chronicles 5D's: Attack of the Dark Signers. Hopefully early on I can nab 2 copies of Majestic Dragon so Yusei can make his Majestic Star Dragon deck.
I have a problem which is seeing items about to expire makes me want to use them all. So I feel like using every key by the time I completed the event and have spares.
I mean if I have time to spare after beating Floor 33 I'll passively farm the Jewls, try to make my copy of Mars into Prismatic, but I'm saving all of my Duel Orbs just for Duelist Chronicles 5D's.
The chronicles event demands more items because it's not easy to get those chalices you need 10 of to fight a super dark signer (or super tower monster depending on which).
The Challenge fights don't become available until like 4 days into the event.
Because I intend to spam the ever loving snot outta that event, I intend to have easily 100+ of those Tickets because I want to get the Sleeves, Skill, Mat, and Icon.
Also hoping to get a couple copies of Majestic Dragon from the Lottery so that I can make Yusei his Majestic Star Dragon deck since I have a Prismatic copy of Majestic Star Dragon (used a Prismatic UR Ticket on, probably going to get one for clearing Round 3, so I probably made a big dumb there, since I don't have any Majestic Dragon as I elected not to get those via various SR Tickets.
And since it's a Tuner, I can return it to the deck and then Special it from my Deck. And then use a Photon Lead to toss out Stardust Phantom to be the non-Tuner.
