During the turn you activate this card, you cannot Special Summon from the Extra Deck

[When Attacking] By returning 1 Digimon card from your opponent's trash to the bottom of the deck, delete all of your opponent's Digimon with the same name as that card

It can make something an artifact permanently, and it plays into any deck's framework where you want to en-artifact your stuff to enhance them with cards like Darksteel Forge or Padeem, Consul of Innovation

(This does not apply to card(s) that are already on the field before this effect started applying.) They cannot be placed on the field

You start off with some early acceleration, generate some card advantage mid-game to keep the creatures flowing, and then close it out with Craterhoof Behemoth or some other trample effect
