Since Overload Summon was lazily written allow me to rewrite that card in better language. 

Name: Overload Summon

Spell type: Normal

Effect: During your Main Phase send the number of cards to the graveyard as listed under the LV/RK of the monster you are trying to summon using this card's effect ignoring said card's summoning conditions. That summon is treated as a Special Summon. When that monster is destroyed in battle or leaves the field remove it from play.

1-2: One Card
3-4: Two Cards
5-6: Three Cards
7-8: Four Cards
9-10: Five Cards
11-12: Six Cards

I doubt this one would be allowable, but still I could see this card being made for the game. Where it does have quite a negative effect that can kill you it also gives you the ability to special summon a powerful monster to the field at the beginning of a duel which is why this card would end up on the Forbidden list. But I still wanted to share this one nonetheless.
