Dylan, wait until the next set comes out, then we can work on a standard.

Actually it doesn't make it unblockable, it just stops the creature from taking damage from the color you pick.

Thus safe passage, as it allows you to do damage, but not your opponent.
Also, you can give your creature protection from creatures, so it wouldn't even be indangered by other creatures with double strike.

Well, look around in the Equipments a little bit, if you get any sort of Deathtouch with the Double strike, anything that blocks that creature is killed instantly.

Understood, just an idea though.

Well, if you want some more cards to possibly add, since you got good attacking with double strikes galore. Maybe Safe Passage can help if your put in a situation of sudden danger, also, instead of just the Ring of Thune, if you want to spend a little cash, Basilisk Collar can be devastating when mixed with Double Strike, a Double Strike/Deathtouch/Lifelink.

I like where your going with this deck, but maybe instead of Hunger Of The Howl Pack, put in 4 Forced Adaptations. And since your doing alot of sacrificing, maybe put in a Deadbridge Chant or two instead of 4 Blessings Of Nature.

I like this deck, it's simple, everything is low cost in mana and price.

Best way to play infect is to hit fast and hard, so try keeping your creature costs below 2-3. And since you are using green, get as many instant buffs like titanic growth and invigorate/mutagenic growth. With the last two make your opponant gain life instead of pay the cost so you can make your single guy attacking a 10+ infect for the one hit kill before the other player can do anything.

Glad I could help ^_^

Well, what about Hypnotic Specter? You have a card that gives your opponent cards, why not make it so they discard as well more quickly, and at that randomly.

Well, how about just 3 Dark Rituals for increased mana ramp.

K, I found a few creature cards, I'll see if I come up with anything in Equipments in a moment.
Haunted Of Nightveil
Lazav, Dimir Mastermind
Mortus Strider
Soulsworn Spirit

Found Whispersilk cloak, can make your other creatures unblockable.

Well, this works very well with invisible stalker. Look up Quietus Spike.

Can it be a Planeswalker still?

To keep with the Cipher theme, maybe Undercity Plague?

Acorn Catapult perhaps?

No problem man.

I personally think Stormbound and Voiceless can be replaced with something more effective when it comes to controlling, perhaps with a Kami, as they do have some interesting abilities. And if your playing pure spirits, then Angel Of Flight Alabaster will let you get the spirits back out of your graveyard and into play. This is my own Spirit Deck, might give you ideas.
