yugioh ep1 card list Watch Yu-Gi-Oh! Episode : The Heart of the Cards inflict damage to your opponents Life Points equal to half of the DEF of the destroyed monster. Exclusive Pack - Yugipedia

This set does have more graveyard stuff and artifacts than normal, so I imagine this will work well enough to be nice in many decks, but its probably not amazing

(You can only use 1 GX attack per game.) Very strong special attack against Ultra Beasts 5th place

I do think their financial impact will be mitigated, but the Bucky incarnations of Emerald-Steel being 22% of the field at DLC Bochum, and usually about that or more at local Set Champs, you went from players ABSOLUTELY NEEDING all of these already expensive Legendaries, to they are nice to have if your deck is better with them. One side note: it is also highly possible that these cards will be used in other decks that Bucky was keeping in check/making impossible to run

Its a pretty wild ability, even for old MTG
