The complete Legend of Blue Eyes White Dragon booster set is 126 cards: 82 Commons 22 Rares 10 Super Rares 10 Ultra Rares 2 Secret Rares
But which cards are mot worth keeping an eye out for
Tapping for a legendary card is awesome, and she has always been able to get something like Kor Haven or Godsend as well as any legendary creature you might be packing
Some back faces have abilities that allow them to transform back to their front faces, but for back faces like Hades, it's a one-way journey, although some other spells and abilities may still cause it to transform back
Reprint risk in a future set is the main thing to watch, since Mew gets printed often
The card gets interesting if youre running Sunforger, but most of the spells Im excited to cast with Sunforger are three or four mana, so the synergy isnt quite there
