[Loki] - Gravestone Golem & Stone Casket Mimic

[Thar]

[b]Gravestone Golem[/b]
[i]DARK / Rank 8 / Rock / Xyz / Effect[/i]
2 Level 4 Monsters
If this card would be destroyed by a card effect: You may detach an Xyz material from this card and destroy the Xyz material; this card is not destroyed.
[i]ATK: 2600 / DEF: 1700[/i]

Whatever is inside the grave requires a sh*t ton of time to get out, but you can't expect its grave to attack you.

[b]Stone Casket Mimic[/b]
[i]DARK / Level 4 / Rock / Effect[/i]
Can only be Special Summoned by banishing a monster you control and cannot be Summoned any other way. When this card is destroyed: Special Summon the monster that was banished by this card's effect to your field.
[i]ATK: 1900 / DEF: 1600[/i]

Last minute idea to support the previous card.

More of a design experiment than anything, but Cnc is always welcome~

So I'm confused by Gravestone Golem. It's a Rank 8 that needs Level 4s? And it starts with 5 Materials and gets 3 whenever you revive it? That sounds abuseable, I'm just not sure how, especially with 2600 ATK.

A few things:
As mentioned, Gravestone Golem looks weird, being a Rank 8 (and you put Level but requiring Level 4 materials.
Secondly, there is an error in its effect, as you cannot destroy Xyz Materials, you detach them, unless this was on purpose (after better consideration, it might be).
But yeah, it sounds abusable.

Stone Casket Mimic is fine.
