interesting yugioh decks Complete Custom Deck for Yu-Gi-Oh! Oldschool Yugi vs. Kaiba mini-format:

When equipped, inflicts equal effect damage to your opponent from battle damage involving Relinquished

It must be Special Summoned from the hand with three Tributes, but it negates the effects of all of the opponents face-up Monsters

Marshmallon is infinitely better than Spirit Reaper (which saw actual meta play) because you took 1000 damage (thats a whole Dian Keto right there) just for crashing into it the first time, and then all you could do was stare at that taunting, silly smile for the rest of the duel or until the teacher pulled you aside because you were being too loud in the library

For example, Normal Summoning White Tiger Summoner will allow you to also Special Summon one level 4 or lower Normal monster from your hand - effectively doubling the amount of summons you have made in a turn
