Soulbound Threatdown (Metashaker #4)
It is really fun to win with a creature that can deal 10-20 damage, effectively putting your opponents on a 1 or 2 turn clock. The biggest problem with decks like this is often hard removal: Frogifies, Nightmares, etc. This deck uses Soulbound Sagami to combo into a wide range of fast, tough, affordable threats to help you get around that problem, while using board clear and movement abilities to get your threats/sacrifice Sagamis past their defenses, and to hopefully keep you from dying before they do. The wide range of threats means that the randomness of the Sagami is less of a problem, since lots of targets work. It also increases the odds that you'll have more big threats than they have removal options. This is a refinement of the Flyin' Soulbears deck.
Aside from a wide range of different combos, the Sagamis +3 (as opposed to the +2 options more common to green) is important in getting you to the magic numbers of 10 and 20, and it makes the various +1s in the deck (from Camp fires and Khalim's Training) much more useful.
The big changes from previous iterations of this idea include the use of Death Walkers, instead of Assassins. The death walkers introduce a third crucial threat, which can become a 10-10 with the help of a Sagami and a Campfire/ Khalim's Training. Lord of the Wastes + a Sagami can get you there all on their own. Ursus can get to 10 with a Sagami, a +1 and a single damage source, and one more damage source takes them to 20. Lots of other good variants with Ursus are available. In all cases, the Sagamis unique bonus is integral to making the combo more efficient.
Side note: mobility is really important in a Sagami deck. Not only does it mean the Sagami is more likely to get a good attack/trade in, but it also helps you deal with the randomness, since you can move whatever gets the bonus into position.
Even more fun to play than previous iterations of this idea, because it wins more betterer good times +1.
