Latch Seeker and Phantom Warrior; your reliance on Invisible Stalker is too great to play only 4 of an unblockable monster.

Split the land 12/11 in favor of swamps. Second, when you're playing 23 lands, you can forget Farseek. Third, Why play only 1 Timberpack Wolf? Fourth, play more Rancor.

Now I feel like an insensitive jerk . . . I'm sorry.

Let me see if I can translate my Germanic friend's plea.

"Why would you choose Volition Reins? Wouldn't Take Possession be better?" ~~ personally, I prefer Mind Control.

"And why a Day of Judgement and why just that? Supreme Verdict and Wrath of God are both better, other . . . um, something . . ." ~~ I have to agree with the German there.
"Trickbind can nix abilities. Why not that? Why not more effects?" ~~ not sure what he means . . .

"Otherwise, this looks pretty 'schick'!" ~~ that, I also agree with.

How do you win, silly goose? The only thing that could damage a player is Fiery Gambit or Essence Backlash, and you need to use about four of them to take down your opponent.

Game of Chaos works great, and you'll definitely want to play four Thumbs and maybe even some Mirror Galleries to make your flip odds go sky-high. And Goblin Bomb is the trademark coin-flip win.

Chance Encounter is another way to win, and you can make sure you get to play nearly everything if you activate Ral Zarek's last ability.

If you're looking for some control power, use Odds from the double-sided card, Odds // Ends.

Lastly, you're not running any one-drops, so feel free to use Izzet Guildgate.

I've seen like four coin-flip decks on the vault; one of the biggest challenges in making coin flip decks is actually knowing the cards. I hope that's the case and you didn't ignore cards like Goblin Bomb, Game of Chaos, and Chance Encounter.

If you need any other ideas, here's my coin flip deck:

Good lands are regrettably expensive.

Pyroclasm for Whipflare.
Great deck!

Copperline Gorge or Stomping Ground or Rootbound Crag for Evolving Wilds.

Dark Ritual to get rats turn 1?

One of the biggest ways to cream your opponent with land destruction is Liquimetal Coating and then artifact disrupters, like shattering spree, crush, smelt, etc.

Stormtide Leviathan, or Island Sanctuary.

That will work about half the time; when the Spitfire is not blocked, and it'll pretty much only apply to instants. With Guttersnipe, it's real damage, rather than a creature which can be destroyed, blocked, or damage prevented. It also can be very hard to keep blockers on your field in some games, and only eight creatures in a deck can be a little underwhelming.

Go for Guttersnipe to convert your spells into raw damage.

Lodestone Golem, Ethersworn Canonist; both help shut down opponents.

You can't have more than one Rakdos Guildgate. Go for Blood Crypt, Dragonskull Summit, Auntie's Hovel, Goblin Burrows, Teetering Peaks, Graven Cairns, Blackcleave Cliffs, Akoum Refuge, Sulfurous Springs, and maybe Rakdos Carnarium, and Lavaclaw Reaches. I'm the land man, Man.

They are so fun, especially in multiplayer casual, which is my favorite format.

Here is my coin deck. Some differences: Mirror Gallery for multiple Krark's Thumbs in play; Frenetic Sliver serves as a perfect chump blocker; Chaotic Goo becomes a verifiable monster; and Chance Encounter works to be a win.

Your mana curve is awful. You'll empty your hand and have to top deck. I recommend Sign in Blood and Altar's Reap.

1. Cut the red.
2. Put in Appetite for Brains. At least on the Sideboard. As a joke.
