Today's card of the day is Worldslayer which is a five mana equipment with an equip cost of five that destroys all other permanents if the equipped creature deals combat damage to an opponent. This is primarily a Casual card as it arrives later in the game and really requires a target with Indestructible, Regeneration, or returning from the graveyard in addition to Trample or evasion to be an effective threat.
A deck in Multiplayer could be designed around it as well, as it is a global effect, though disruption and being targeted by the rest of the table is highly likely. In a Casual setting against a single opponent this can be more difficult to oppose and offers a fairly unique theme to design a deck around.

In Limited this, to state the obvious, is a double-edged sword that resets the game with just this remaining in most situations. It is highly situational and can be difficult to draft support for in the format as it depends on other effects to really gain an advantage. Even as an artifact it is a difficult first pick in Booster as without support it is a higher cost coin flip that slows down the game more than Wrath of God. It can reasonably be passed depending on your style of play and barring a very beneficial pool can be sidedecked in Sealed as well.

Worldslayer

This is the stuff combos are made of.

It's a lot of fun to put this on something an opponent can't block and destroy everything - even land. The key to the combo, of course, is to have something either indestructible or that comes back after the world-slaying effect.

It's a bit much to pull off reliably in a constructed deck, so as with most combo cards, it's relegated to the world of casual play. But what a powerful casual card it is!

In a multiplayer game, there are few better ways to draw the attention of other players than to play this. Players that are struggling suddenly become your friend, hoping you'll wipe the board and give them a fresh start. Players who are in a good position will do anything they can to keep the worldslayer from foiling their plans and giving opponents a chance to come back.

The fact that this destroys ALL permanents including land is pretty unique. If you're playing it, make sure you have some way to play this to your advantage - either the aforementioned creature who will be around after the slaying, or a way to guarantee you'll get more land more quickly than an opponent so you can build your board back more quickly.

Closing things off for Weapons Week, we have a sword that can destroy the world.

Today's weapon: Longsword
Trivia: The longsword was a quick, effective, and versatile weapon capable of deadly thrusts, slices, and cuts. The blade of the longsword is straight and double-edged, and over time longsword blades became slightly longer, thicker in cross-section, less wide, and considerably more pointed.

When they called this sword Worldslayer, they really made sure it lived up to its name. This sword is POWERFUL. The slightest cut and it destroys everything. But then surely you knew we'd save something really strong for our final card. Worldslayer ends worlds.

Unfortunately, "powerful" and "strong" don't necessarily mean "good." Worldslayer, as it turns out, is probably the least playable card we've looked at during Weapons Week. Moonsilver Spear only needed to attack, and Umezawa's Jitte just needed to deal combat damage and didn't care to what. But Worldslayer actually needs to hit your opponent, even if just slightly. 1 damage is all it would take, be it some extra spillover from trample or an unblocked (unblockable?) 1/1. Oh, and it costs 10 mana to even try.

So what makes it worth it to try? Should you even bother? Why yes. Yes you should. Because IF you hit with Worldslayer even once AND you've got the right stuff out in the right deck, you've won the game. Period. Take a look at that ability again. "Destroy all permanents other than Worldslayer." What does that even mean? It means all creatures, gone. All enchantment, gone. Artifacts, gone. Planeswalkers, gone. LANDS, gone. You blow up EVERYTHING that anyone had, and they can't even recover because they've got no lands left next turn.

But wait, Worldslayer kills your stuff too! Doesn't it? Well, yes and no. And your goal is to make it as much "no" as possible. There are cards, cards you could make a deck with, that wield Worldslayer without any fear. For they are cards with Indestructible. Or Regenerate. Or maybe Totem Armor. Or guys that come back from or like being in the graveyard. Or that do something cool when they die like create tokens. Bestow doesn't work, sadly. But the good news is you don't even need these things permanently, only the turn you attack and plan to hit the opponent with your fancy sword. Things that give your guys regeneration or indestructible just for the turn, like Boros Charm, would work quite well.

There's still the matter of that 10 mana. 5 to cast and 5 to equip is pretty steep, even more expensive than Moonsilver Spear. That's like 90% of what makes this card unplayable. The rest is no power/toughness boost or evasion, and the fact that you have to deal some combat damage to the opponent with it. That's not always easy. Clearly this is a job for the Puresteel Paladin + guys with evasion combination we talked about earlier in the week. And while we're talking about Moonsilver Spear, the lady who wields it - Avacyn, Angel of Hope - actually likes Worldslayer quite a bit as well, since she gives all your stuff indestructible. Plus flying doesn't hurt. Or you could just throw caution to the wind and put this thing into the hands of a Darksteel Colossus. THAT'S always fun. Let's see them try and stop that thing!

So let's recap. Somehow you've gotta cast this for 5 mana, sneak it onto an Invisible Stalker with Puresteel Paladin, make all your stuff temporarily indestructible with Boros Charm (or permanently with Avacyn), and then you've won the game because your opponent is basically reset to turn 0. No lands, no creatures, nothing on their side of the field at all. They've been worldslain.

It's an 11 mana and 4 cards (or 18 mana and 2 cards) combo that more or less boils down to a one-sided field wipe. You know, assuming your opponent sits there twiddling their fingers letting you set it all up and then attack them without responding.

It's also fun. I'll give it that. It's complex and convoluted and difficult and expensive and really maybe a tad completely unnecessary. But it's very fun. If you're into that sort of thing.

They don't call this sword Worldslayer for nothing.

That's it for Weapons Week folks. Hope you enjoyed it!

Welcome back readers todays card of the day is quite flavorful and has a powerful effect. Being able to reset the game minus this equipment can be devastating. In constructed formats this card is just too slow as you need a ton of mana to play and equip and then be able to get through with a creature making it a long shot that’s hard to make work. This card in casual and multiplayer can be devastating, resetting the game for no other reason than to reset it is often looked down upon and will make you a quick target for revenge, however combined with suspend creatures or creatures that bounce or exile themselves this card can be devastating way to insure you win the game in short order. In limited its pretty much unplayable as you have no real way of building around its effect aside from hoarding cards in your hand to have a better position after it blows up. Overall a card meant for casual play and one that needs to be played carefully to insure max effectiveness.
