62 x 89 card sleeves CheckOutStore Double Matte Protective compatible with Yu-Gi-Oh, Cardfight Vanguard (62 mm) [Discontinued] you get enough protection for most Japanese Ultra Pro Deck Protector Sleeves:

UR Ultra Rare UL Ultimate Rare Maximum Six X EARTH Level 6 [ WarriorEffect ] ATK 1900 DEF 1600 When this card is Tribute Summoned: Roll a six-sided die, and this card gains ATK equal to the result x 200

The tool fetches the decklist via the site's API, enriches each card with Scryfall data, and computes 12 factors: premium fast mana, common fast mana, tutors, interaction, combo pressure, extra turns, mana efficiency, ramp, draw, curve health, land base, commander synergy, and game changers

I would recommend buying a magistus core instead, but we don't know exactly what the chronicles deck will contain, you don't want to pay $20 per femboy and $30 for the one aleister only to see them reprinted later on as dollar ultras

You're pretty bright
