yugioh cards made 500 Assorted Including Rare, Ultra Rare and Holographic Cards : Toys & Games Yugioh Fan-Made Cards — Metalfire127's

Its as if the designers tried to say: Hey, if youre bad at deck-building, heres at least some extra health for you. A good deck utilizes mana very accurately, and you almost never should end up with excess mana, unless something totally unexpected happens

The full set contains 63 cards plus 12 AR, 9 SR, 5 SAR and 3 UR cards (Total of 92 cards in the set)

And in case you forgot, we typically get seven versions of every Standard rare / mythic as a baseline: a regular and a foil printing from boosters, an extended art and an extended art foil from Collector Boosters, a timestamped prerelease promo in foil, and a foil and a non-foil planeswalker stamped version from the Promo Packs

This means you probably won't get stuck with the card if you don't need it
