When an opponent's monster declares an attack: You can send this card from your hand to the Graveyard; change the attacking monster to Defense Position. When you Ritual Summon a monster, you can banish this card from your Graveyard as 1 of the monsters required for the Ritual Summon.
One of the staple cards that works very well in any kinds of decks in current card pool due to capability of playing two roles: defending your monsters from being attacked and being a material for ritual summon when it is in the graveyard.
Can be used from your hand and it cannot be negated by most spell/trap cards.
Whoever invested his /her gems in this card back in the day when Ultimate Rising was released must be really pleased because pretty much all top tier decks have lots sphere kuribohs in them. Except blue eyes, 'cause totally aggressive decks don't need to stall ofc.
Most bullshit card. My opponents always get this shit in their starting hand on first turn. when i check their deck, they only have ONE this card. Most time i could finish duel with OTK, but because of this bullshit card i end up losing. RNG SHIT
