Filibuster!

Filibuster!
[ Spell / Quickplay ]
Activate only when a monster you control would be destroyed. That monster is not affected by Spell, Trap, or monster effects, and cannot be destroyed by battle until the end of the turn. During the End Phase of the 2nd turn after this card was activated: Send that monster to the Graveyard.

I think "unnafected" is used instead of "not affected".

Overall, a cool combat trick, but in Yugioh, it is easy to find better options I guess.

A generic Pandemic Contagion Infestation is pretty nice though, even if for just one monster.

Card text should be "other Spell", instead of just "Spell", in the first line. Mostly, you don't want the card to read that it contradicts itself and doesn't work O,o
