Paunuku Knight inspired me to make this one: Reverse Cardmaster

[Eddie McBean]

 

While you control this face-up card, you and your opponent are unable to attack any monsters except their own. This card can't be destroyed by battle by monsters you control, once per turn, pay 500 LP to special summon one level 6 or lower effect monster to your side of the field from your hand, but its ATK and DEF become 0. Discard 1 card during each of your standby phases or destroy this card and draw 1 card.

 

Breaking all logic and all decks that resolve on battle damage, Reverse Cardmaster at your service XD

[Kanashimi]

this should be moved to experimental imo . . . (looking at the eff and the type)

 

that artwork seems familiar . . . is it Gumi form Dead Line Circus? that's why i'm here upupupupu . . .

 

The wording you write seems a bit weird, unable to attack except its own monster they own means universal attack stop, since no game mechanics that allows you to attack your own monsters, except by effect.

 

Maybe this is what you looking for:

"During each player's Battle Phase, each player can only attack their own monsters they control, if it does, apply damage calculation normally. Once per turn: You can pay 500 LP; Special Summon 1 Level 6 or lower monster from your hand but its ATK and DEF becomes 0. During your Standby Phase, discard 1 card or destroy this card. If this card is destroyed by this way: Draw 1 card."

 

What i hate is the first part of the eff, support stall.dek and the 2nd . . . . ummmmm maybe too generic, change it to specific monster type or attri.

Neither player can attack monsters, except monsters they control. Cannot be destroyed by battle with monsters you control. Once per turn: You can pay 500 LP; Special Summon 1 Level 6 or lower Effect Monster from your hand, but its ATK and DEF become 0. During your Standby Phase: Discard 1 card, otherwise destroy this card. When this card is destroyed by its own effect: Draw 1 card.

 

Closest equivalent to Magician is Spellcaster, so that's what I'll treat this as.

There really is no need for you to make an explicit new Type, if that was intended.

 

In any case, this is sort of like that anime Field Spell from GX, Training Field if I remember.

(Because that card is written in old style OCG, going to be a pain to convert it)

 

-----

But in any case, the SS effect should not be generic, and should have restrictions.

Change it to either be Type specific or lower the Level of what you can summon; especially since a lot of cards are capable of mass summoning upon their own (or other stuff).

 

Otherwise, there are some crazy things that can be done here with the card (Battle Mania is one thing; another would probably be some weird thing with Amazoness Swords Woman [which transfers the damage to the opponent]).

 

Also keep in mind that the creator of Paunuku Knight is known for designing very awkward cards that range from impractical to bordering on the edge of OPness.

That's what I aim to do Sakura, to be honest I forgot Spellcaster was a thing when I made this card... XD brain farts... they happen. And yeah, I basically post here to get opinions so I can polish my card (probably making a whole reverse deck to be honest). Will post the new Cardmaster soon enough, be eager because this card is going to become quite an tricky card to deal with :P

 

Oh, and Party yen Party (Don't have the yen money sign in my keyboard, so deal with it). Yes, it is Gumi.

 

There we go, new, improved and probably still pretty awesome:

 

 

While you control this face-up card, you and your opponent are unable to attack monsters of the opposite side of the field. This card can't be destroyed by battle by monsters you control, once per turn, pay 500 LP to special summon one level 4 or lower effect monster (of the same attribute of this card on the moment it uses this effect) to your side of the field from your hand, but its ATK and DEF become 0. Discard 1 card during each of your standby phases or destroy this card, and if this card is destroyed that way: draw 1 card.
