yugioh master duel sacred beasts deck Complete Custom for Yu-Gi-Oh! GX Yu-Gi-Oh! Trading Cards: Sacred Beasts

Tristan loses the duel to protect her, sending her into a state of shock, feeling responsible for getting him involved in the first place

When a card or effect is activated that targets this card on the field, or when this card is targeted for an attack (Quick Effect): You can Special Summon 1 "Blue-Eyes White Dragon" or 1 Level 1 LIGHT Tuner from your GY

Also, when this card is Normal or Special Summoned, you can place one Sinful Spoils spell or trap card directly from the deck

If things had stopped there, perhaps it would have been fine, but, eventually, they introduced tuners that could come back from the graveyard, creating near-infinite fodder to create larger fields
