Diamond

&nbsp The Diamond monsters are a series of Effect Monsters that overwhelm the opponent with their immunity from Spell and/or Trap cards. I have designed these card so we have a back story for the afterlife.

Trap Cards and Spell Cards tend to be some of the most common cards used by players (obviously), and the Diamond Archetype focuses upon preventing your opponent from using them to counterattack.

Legend of the Diamond Monsters
When the Spirit World was created soon "The Original One" created a beind to guard that world. To make sure no living mortal made it in an no soul leaves. This creature is known as "Diamentes, King of the Spirit World". Diamentes soon created an army of monsters to aid him in capturing any mortal who's time is up and any soul who managws to escape. He then gave them Supernatural powers so that their strength would be unrivaled against any opponent and to protect the Spirit World from destruction. Now they have been unleashed after 5000 years, tthe last time anything escaped to capture the only creature to have ever escaped the Spirit World.

Strategy
The simple strategy for Diamond monsters is to play the card "Diamond Mine" thereby allowing them to be on the field for more than one turn. The Diamond monsters get more effective as you go on so in a duel it is better to take your time with this Archetype as your opponent will get weaker when going against these cards.

You can use "Cost Down", "Star Blast", "Mausoleum of the Emperor" to make the normal summoning of higher tier Diamond monsters easier.

If you can hold out for long enough you can activate the field Spell "Convexity" and Normal Summon the leader and trump card for this archetype "Diamentes, King of the Spirit World" which is pretty much an instant win.

Weaknesses

 * You must have at least 3 of the card "Diamond Mine" to have an effective Deck as these monster will only be on the field for one turn otherwise.
 * Though formidable, the Diamond monsters are not invincible as cards with removal abilities can be a seroious threat.
 * You opponent obtaining control of your Diamond monster is possibly the worst problem ypu can face as they can use most of their effect against you and you lose the monster as they will probably not posess a "Diamond Mine".
