Negative Numbers

[mr. waifu]

This is a new series of monsters I have created that are an opposite version of the "Number" Xyz cards. They gain effects that are a complete opposite of their original monster. Here are some examples:

 

Number -9: Dyol Trapezium

Rank 9

DARK

3000 / 2800

Machine / Xyz / Effect

2 level 9 monsters

Once per turn, when this card attacks while it has Xyz Materials, your opponent can not activate effects until the end of the damage calculation. If this card attacks while it has no Xyz Materials, you can target 2 monsters in your Graveyard, and attach those cards to this card as Xyz Material. Once per turn, you can detach 1 Xyz Material from this card: All monsters you control can attack directly this turn, except this card. Your opponent must have at least 2000 more LP than you in order to activate and to resolve this effect.

 

Number -20: Giga-Maniax

Rank 3

DARK

1900 / 1900

Insect / Xyz / Effect

2 level 3 monsters

Once per turn, you can detach 1 Xyz Material from this card. While this card is face-up on the field, your opponent's monsters lose 300 ATK and DEF for every time you detach 1 Xyz Material by this card's effect.

 

Number -30: Water Golem of Healing

Rank 3

WATER

3000 / 3000

Rock / Xyz / Effect

2 level 3 monsters

During your Standby Phases, detach 1 Xyz Material from this card, and if you do, your opponent gains 2000 LP. This card can not attack while this card has Xyz Material. You can not Special Summon from the Extra Deck.

 

Number -39: Arkalpria

Rank 4

DARK

2500 / 2000

Spellcaster / Xyz / Effect

2 level 4 monsters

When either players monster would change battle position: You can detach 1 Xyz Material from this card: That monster can not change its battle position. If this card attacks while it has no Xyz Material attached to it: Destroy this card.

 

Number -101: Shining Honor ARK

Rank 4

LIGHT

2100 / 2000

Fairy / Xyz / Effect

2 level 4 monsters

Once per turn, you can detach 2 Xyz Materials from this card, and equip 1 of them to your opponent's monster. While equipped, it can not attack, and its ATK and DEF become 0, unless if it was Normal Summoned. You can only use this effect once per turn. If this card would be destroyed, you can destroy the Xyz Material that was equipped to that monster instead.

 

Plz CnC!

Not on board with -9 being able to recover its materials once it runs out, especially when it's attacking and out of the blue, gains Armades's effect. I'm fine with it having that lock while it has mats though. Although, looking at the original Dyson Sphere, it does the same thing (though in this case, you're getting the effect when you attack instead of this being attacked). In any case, it's essentially an OTK enabler; especially if you have your board set up properly (or at least close to it). Rank 9 is still difficult to make though. 
 
-20 is meh to be honest. Granted, original 20 didn't do much either bar for a minor power boost. Also given the gamestate, monsters will be leaving the field for ED / Pendulums very quickly, so the drop won't really do anything. 
 
-30 is literally a free 3K beater if you CoTH it or use something like Oni-Gami Combo to remove its Xyz Materials so your opponent doesn't get the 4k LP from the effect. Given the wording, this is a mandatory effect (like original 30 is). Though, at least you can still SS monsters (just not from the Extra).
 
I really don't know what Decks can even use - 39 in this current gamestate. Suppose you can use this in conjunction with Book of Moon or something to keep the opponent from moving. 
 
-101 is worded weirdly, but it essentially detaches all its mats and forces one of them onto your opponent's monsters, making them a 0/0 bait. Monarchs don't really care about this card forcing a mat onto them (or really, anything that doesn't rely on SSing much). Unlike the original 101, this card relies on the opponent not using something like Twin Twister or something to get rid of the mat (though it does restrict your opponent's backrow setting in the first place, so guess that's worth something).

First off, let me comment that I was expecting something more interesting than this for this great concept. I mean, yes, reverse effects/stats are cool and all, but I was expecting something unique in terms of summoning mechanics or something or other.

 

-9 Armades effect is really neat when combined with the slightly higher ATK. R9 is hard to make, however, it is buffed by the fact that this card can recycle materials endlessly. It's a really powerful effect, allowing you to recycle cards like Kurivolt. Bad Example, true, but if you can detach Xyz Materials from it to activate effects, you can recycle those effects endlessly. Attacking directly is perfect for OTK city. I don't know if there is a generic way to Summon this card, but still, it could be a threat.

 

-20 rather weak, which reminds me of another ATK changing card. Number 20! While Number 20 was marginally more useful for you, as you tried to keep your monsters on the field, 300 ATK is not doing anything to your opponent, and they be leaving the field very soon if you attack, so not worth it at all.

 

-30 forces you to detach an Xyz Material, or....nothing? It buffs your opponent? Unlike Acid Golem, in which you could keep it for as long as you wanted providing you were willing to take the damage, this forces you to detach the Xyz Material regardless, and heal your opponent regardless, with the only debuff when you've lost this card is that you can't attack, and the SSing limitation only applies to the Extra Deck, so it's not even that much of a debuff. I mean, this card is no fun to give to your opponent, considering nothing will happen once they run out of Xyz Materials. Change it to detach or your opponent gains, and that might work better.

 

-39 reminds me that the stat changes in these cards only happen occasionally, and aren't even always for ATK/DEF reversing. Why couldn't that be a thing, especially with offensive cards that could get defensive? Also, this card's effect sucks. Sorry for it to sound harsh, but its not like preventing your opponent from changing their battle position isn't such a big thing, as they can just summon in that position they want to begin with. 

 

What does -101 do? It is worded confusingly.

What does -101 do? It is worded confusingly.

• Detaches its materials like regular 101
• Equips one of the detached mats to a monster of user's choice (so no targeting). It'll equip like a normal card.
• Unless monster was NS'd, said monster cannot attack and it's a 0/0. 
• Can use the equipped card to avoid destruction. 

As for -9, I did say that it was an OTK enabler. Regarding any summoning, I guess one could use Marshaling Field or something to get it out in Puppets or whatever Machine deck that can run R5 - 9. I looked for any Astral Force targets; none exist. Or Xyz Universe if you really want to go there.

K thx for the reviews, but just in case if you didn't read it properly or not, -20 affects all monsters your opponent controls, but not just the current ones, but the ones that come back into the field. Also I'll take your advice and change the latter and before monsters a bit.
