Gachi Gachi, Maestroke, Zenmaines and of course Tiras Keeper of Genesis.

We're now looking at a tier1 Malefics deck.

Oh, also, nice going KONAMI, making psychic plays with Ultimate Axon Kicker a thing that we cannot overcome now.

I see no advantage from the seal?? They should make it on DN when the epic music starts playing and the seal locks in place xD. If they make the seal a card they should make the legendary knights/dragons real :p.

Here's the full effect of the seal of orichalcos:



When this card is activated: Destroy all Special Summoned monsters you control.
You cannot Special Summon monsters from your Extra Deck.
All monsters you control gain 500 ATK.
Once per turn, this card cannot be destroyed by card effect.
While you control 2 or more face-up Attack Position monsters, your opponent cannot select monster with the lowest ATK you control as an attack target.
Each player can only use the effect of "The Seal of Orichalcos" once per Duel.

They managed to fuck it up. Only 1 per duel...? What is this? Well, it maybe is for the best, this way it won't be OP, even for Malefics.
