UR Ultra Rare Deep-Eyes White Dragon X LIGHT Level 10 [ DragonEffect ] ATK 0 DEF 0 When a face-up "Blue-Eyes" monster(s) you control is destroyed by battle or an opponent's card effect, and you have a Dragon-Type monster in your Graveyard: You can Special Summon this card from your hand, and if you do, inflict 600 damage to your opponent for each Dragon-Type monster with different names in your Graveyard

There are situations where you can mitigate the downside

The obvious card that desperately can use this mana ability is Golos, Tireless Pilgrim

So if your opponent is a new player or makes a long list of mistakes in game one, maybe you shouldnt keep a risky hand in game two
