Dynamic Block Monsters / Arm is using the cardmaker again?

Been ages since I've done something like this.

[quote][center]Cannot be Special Summoned from the Graveyard. If a Rock-Type monster, except "Dynamic Rock Monster - Iron" is destroyed as a result of battle, you can Banish the Destroyed monster: add this card from your Deck to your Hand. If this card is Tribute Summoned, the Tribute(s) must be EARTH. Once per turn you can Discard 1 Rock-Type monster: Increase the ATK of this card by 300. If this card destroys an Opponent's monster as a result of battle, you can Target 1 face-up monster on the field: Destroy the Target. If this card is destroyed by your Opponent's card(either by battle or card effect): Target 1 other Rock-Type monster in your Graveyard: Return the Target to the bottom of your Deck.[/center][/quote][/center][/spoiler]

If I've gone a little overboard with any of these, I will make changes accordingly.

Decided to turn this into somewhat of an archetype.
