Forbidden Lance, a Quickplay Magic card that makes a monster (whilst face up on the Field) impervious to Magic and Trap cards, until the End Phase, by reducing said monsters attack by 800 points.  First, that is totally a spear, not a lance...maybe that's why it's forbidden?
 
So, let's say this is being used on Synchro Monster, or something else powerful, say on average maybe with 2500 attack.  Now you have a monster with 1700 attack, quite easier to destroy, but if you're going to destroy a monster to start, why don't you use a card that will do that instead of this?
 
Even if you all ready had an answer to destroying said card, you can't use it until the turn after you use this, remember?  I'm not really thinking this is all that worthwhile...
 
1.5/5 all, again

Forbidden Lance wants to become the next Book of Moon. Forbidden Chalice didn't work quite as well. With the Lance, any monster loses a few ATK points, even the opponent's. Or, you can use the protection effect on your own monster. Book of Moon is a weak card, but its versatility is what makes it a top-tier card. Could Forbidden Lance do that, too?

That depends. It attacks or defends, but when it defends, that monster won't be able to do much. I would say that the ATK reduction, in combination with the protection, makes the card versatile enough to warrant a spot in your deck.

4/5

Hey, Pojo, Assailant here with another Card of the Day for you. Today's card is a quick-play, spell card called Forbidden Lance. This card allows you to select one face-up monster on the field, and, until the end phase, have it be unaffected by spell or trap cards.......at the cost of losing 800 ATK. Now, losing 800 attack is nothing to sneeze at, which can actually be a good thing with this card. WHY?? I'm glad you asked. The reason being, this card says 1 face-up monster which translates to: ANY face-up monster. That means your opponent's as well. So, if your opponent's monster is swinging at you, you can use this card to lower their ATK by 800, usually a fatal happenstance for said monster. It can also be used to make one of your monsters immune to magic and trap for a turn, generally more useful thing on your turn when your opponent’s monster can't run over your -800 monster and you want to avoid their nasty back-row. That being said, if need be, it can be used when your opponent plays his Dark Hole, Smashing Ground, etc.
See? Versatility FTW.

Today's card is possibly the most hyped single card in Storm of Ragnarok. Forbidden Lance is a Quick-Play Spell, reminiscent of Forbidden Chalice. The Lance will decrease the attack of any monster by 800, and leave that monster entirely unaffected by other Spell or Trap cards until the end of the turn.

Where do I start? This card is simply put, amazing. Firstly, 800 ATK is enough to take out plenty of threats. Stardust Dragon becomes a measly 1700, Brionac is a perfectly manageable 1500, and most 3- or 4-star monsters are now weak enough for Sangan to defeat it.

We've had ATK buffs and debuffs for quite some time, and they haven't made an impact on the competitive scene for quite some time, outside Kalut and Honest. This is where Forbidden Lance stands apart, because you can use it on any monster (including your own) to keep it completely safe from Spells and Traps. Your monster will be weakened, but completely immune to Mirror Force, Bottomless Trap Hole, Dark Hole, Mind Control, and even Counter Traps like Solemn Warning and Gladiator Beast War Chariot (Just remember that you must play Lance before those are activated, as they are Spell Speed 3). You can also use it on your opponent's monsters, to make them unaffected by Equip or Field Spells for the turn, as well as getting the ATK decrease. For the first time since Imperial Order, we have a reliable, splashable counter to Book of Moon. Thanks to Forbidden Lance, your Synchro Summons will go unopposed.

Forbidden Lance can be easily splashed into all kinds of decks, but it should be noted that it is especially good in Gladiator Beasts. Not only do they need all the protection they can get, but they can abuse that 800 ATK decrease probably better than any other archetype.

Traditional: 1/5 It probably won't be so useful here, the game is too fast paced.
Advanced: 5/5 Suddenly, those Books of Moon are looking a lot less appealing.
