Game placement capitalization: Graveyard, Deck, Extra Deck, Field Card Zone, Monster Card Zone, Spell/Trap Card Zone, hand, banished

And Tribute Summon from the Graveyard? Like, with this for said card effect:

"Once per turn, you can: Target 1 Level 5 or higher monster in your Graveyard that can be Tribute Summoned. Tribute a number of monsters equal to the number of monsters required for the Tribute Summon of the target. Then, Special Summon the target. You cannot Normal Summon/Set the turn you activate this effect."

If that's the case, then I see no problem with it.
