booster box 25th anniversary Yu-Gi-Oh!: Wild Survivors! — Game Haven Yu-Gi-Oh! 25th Anniversary Rarity Collection

Your opponent takes any battle damage you would have taken from battles involving this card

If you arent one for deckbuilding and still want to give it a shot there are pre-constructed decks suggested by FFG and you can find lots of help for decks, no matter the size of collection, on the excellent ArkhamDB (Im linking a friend of mine who has put together some great decks, but there are loads of folk doing great work on there)

However, since it's fan-made, it's not immediately obvious how to access it
