You can't sac an Augur the turn he comes into play unless they errata'd the text to change it from "only play this during your upkeep".

I would suggest running Groundswell instead of Predator's Strike.

Your Turn 2 Win combo doesn't work because you have to sacrifice Llanowar Augur during your upkeep, and you can't cast it until your main phase. But that really doesn't take away from the rest of this deck, it's very nice for a very nice price. It's got a solid game and a very terrifying early game. But I hate you for playing infect. +1!

Also, this deck works very nicely as a Pauper deck, as all of the cards have a Common printing.

SomeJustice, Grantley91, Thanks for the suggestions. I'll run groundswell, and take out 2x Predator's Strike and 2x Llanowar Augur.

I have recently built a simic infect deck, and everyone seems to forget Virulent Sliver. I would put it in place of Blight Mamba, since infect decks need to be fast. You will almost never use the regenerate ability anyway, since you need to stay aggressive.

Virulent Sliver's ability will only put 1 poison counter on the opponent whenever it deals damage. Infect replaces it's combat damage with poison counters, poisonous 1 gives the player 1 poison counter when they get dealt damage by a creature with poisonous 1.

In other words, putting Giant Growth on virulent sliver will result in 4 damage and 1 poison counter.

To replace the sliver, I think you could use 2 Become Immense and 2 Titanic Growth. Also, Apostle's Blessing is WAY better than Unnatural Predation. Unblockable will more often get the kill than trample does, and it can also serve as a counter to those nasty Lightning Bolts.

Thanks for the suggestions!
