yugioh card dark renewal : YGLD-ENB00 1st Ed Secret Rare after card for players looking to enhance their dark magician deck Dark Renewal - Speed Duel:

How does this affect me, the player

Four-Color Omnath For simplicity Ill call this deck Four-Color Omnath instead of control, midrange, or elementals

The problem with Battle of Wits is that when you consider you will need 200 cards in your deck once it hits the battlefield and that it might take several (or many) turns to get Battle of Wits on the battlefield, you will need to play somewhere around 240 cards to make Battle of Wits work, which means you're increasing your deck size by 300%, which in turn leads to a massive drop in consistency, to the point where Battle of Wits simply isn't worth the cost in competitive decks

And then, as a Quick Effect, you can banish it to Synchro Summon an actual Red Dragon Archfiend from your Extra Deck, double its ATK, and make it immune to your opponents destruction effects
