A token deck where the tokens are used to burn your opponent rather than just populate the board.
--Strategy--try and get Impact Tremors out ASAP, this Enchantment will enable you to use your token spawners as burn cards, rather than merely just populating the battlefield.
After Impact Tremors your next most important spell to get out will be outpost siege. The most common issue with most token decks would be that the tokens are easily removed. Outpost Siege will help you with that issue. Using the Dragon's ability on Outpost Siege will make your opponent think twice before dealing with your hoard. If they kill a token they are dealt a damage from Outpost Siege. The best part of Outpost Siege is that it does not matter if your tokens are put back into your hand, destroyed, or exiled. If they are removed they deal 1 damage to target opponent or creature.
While you may be tempter to always put Outpost Siege down and declare dragons, it is not always the right move. If you have a small board, or see top decking in your near future, you should declare Khans, remember that there are 3 outpost sieges in your deck, and the ability to create more token will often times be better than being stuck with only the ability to spawn in 2 tokens each turn, which are used as chump blockers, and will end up preventing you from being able to keep up with your opponent.
Descent of the Dragons Should be able to end the game, without the dragons ever actually attacking. When the Tokens are destroyed this will trigger Outpost Siege, this should deal X amount of damage to target opponent where X is your number of Tokens. Than when the dragon tokens come in, Impact tremors will deal X damage to all opponents. This means if you have 6 tokens out, you will be removing all of them dealing 12 damage in total, from both Impact Tremors and Outpost Siege, than you have 6 4/4 dragons on the Field. that should be quite enough to kill your opponent next turn.
