If you can cast Pasifism and Stab Wound on one creature it would be an interesting thing because you are putting your opponent on a sort of clock, unless he uses removal on his own creature, but I have no idea how effective it would be in real play.

Wring Flesh isn't that good as removal, it can be used as combat tricks, but I would suggest using cards like Doom Blade , Ultimate Price , Celestial Flare or even Devour Flesh . Avenging arrow is okay removal with one problem : your opponent's creature has to do combat damage first before it can be destroyed, yes you can chump block with your little dude and kill his big creature that way but it is still a 2 for 1 situation which isn't a good thing.

Also one more thing, you need to drop a few lands, 28 is just too much, I'd suggest playing 24. You can use those 4 spaces for more creatures.

I actually played against a friend shortly after making this version of the deck, and noticed this problem. I'm going out to my local card shop to get some of the cards in the Maybeboard, and I'll definitely toss out some lands to make room for them.
