Forum:Next Extra Deck/Special Summon method

I Know Arc-V is nowhere near being done yet but I think it's already time to start speculating:

Lock and Key summon.

Lock Monster: Placed in the Extra Deck, unknown border color, can only be summoned by effect of a Key Monster.

Key Monster: Place in the Main Deck, effect and Normal monsters. Are used to Unlock the Lock Monster in the extra deck. Can be used for other things. SwordoftheSpirit (talk • contribs) 05:58, November 2, 2014 (UTC)
