While this card is face-up on the field, all effects of Spell, Trap, and Monster Cards that target a card(s) in the Graveyard or that activate in the Graveyard are negated. If you have 1 or fewer cards in your hand, this card gains 500 ATK.

This card is used to Ritual Summon "Black Diamond Monolith". You must also Tribute monsters whose total Levels equal 8 or more from the field or your hand."

This card can only be Ritual Summoned with the Ritual Spell Card, "Alchemist Mage of the Darkest Diamond". You must also offer monsters whose total Level Stars equal 8 or more as a tribute from the field or your hand.

"Fireblood Sickler" + "Black Diamond Monolith"
You can remove up to 5 Monster Cards in your Graveyard from play to increase the ATK of this monster by 200 points for each card removed from play until the end of your opponent's next turn. This effect can only be used once during your turn.
When this monster is destroyed as a result of battle and sent to the Graveyard, by paying 1000 Life Points, look at your opponent's hand and select 1 Monster Card from it. Add the selected card to your hand, and you can use it in this Duel. (When the card is sent to the Graveyard, it is sent to the Graveyard of the owner.)

Pretty good for someone who just joined. Though, i would change the effect of the last one. Change it to just "Add the selected card to your hand" and your golden.
9/10.
And welcome to YCM.
