yugioh card locket PENDANT The Seto Kaiba Locket by

Cramped Vents deals six damage to a creature, and you gain life equal to any excess damage

This flexibility greatly increases the value of the card: it allows you to enjoy the advantage that life provides as a form of payment in the early stages of the game, without this becoming a burden in the later stages

cards are noticeably smaller

The ultimate flex for any player would be to create a deck where all the Energy cards are secret rare ones as not only does it cost alot, but it also looks phenomenal too

This means it's not possible to cheat creatures into play out of nowhere (which madness can do), but it also means you're granted more flexibility, because you can cast a spell for its mayhem cost at any point during the turn in which it was discarded (rather than having to choose immediately as per madness rules)

Its not uncommon to have games where it draws you 5+ cards before someone drops a removal on it
