Anti-Matter Cards

[Horu]

Anti-Matter monsters utilize a mechanic called Anti-Summoning. This is because the Anti-Matter monsters begin the game Banished face-down. So the card ultimately starts out blank. This means to Anti-Summon, you have to pull the desired card using an Anti-Draw Spell Card. The Anti-Monsters are like normal monsters except the fact that their Level/Rank is negative. Ant-Matter monsters inflict Negative Battle Damage. So the equation works like this: -2500-2500=-5000 so 8000-(-5000)=13000. But this rule only applies when they are attacking. But here are a few examples:

umm... interesting...? I mean its negative levels and light/dark blue mix (which we've seen before in Dark Synchro monsters) Also the idea of Negative ATK & DEF values is something quite strange. (As is the concept of healing your opponent by such unholy values) I have an Idea for a field spell and an equip spell for these monsters. 

Field spell Idea:

When this card activates, you can discard any number of cards from your hand, for each card discarded by this effect, you can special summon 1 random Anti-Monster from your Banish Zone. As long as there is an Anti-Monster on the field, all effects that would increase their LP is converted into damage, instead. 

Equip spell Idea:

Equip only to an Anti-Monster. The Equipped Anti-Monster loses 1000 ATK and DEF. When the equipped monster battles, neither players monster is destroyed, and neither players LP values change. After damage calculation, Both players Gain LP equal to this cards Negative ATK or DEF value.

Well, the negative damage only applies when the Anti-Monster attacks. So while normally, an attack against a monster would "heal" you, a direct attack heals your opponent.
